  1. Dial on top should equal thermostat I think. My room is insulated so it tends to stay a little warmer anyway. If you don't have insulation in the roof or walls, you can always insulate the tank with polystyrene or wrap it with towels.

    No red would be nice, but you can always look to introduce red-loss or nr1 in a future generation to remove it. I think I have both genes floating around in my recessive line. Down the track we can look at getting a pair over to you
  3. Health wise - F1 was painfully slow in growing even though I committed to daily significant water changes, and 4x feds. F2 seems to be going the same way. Very slow in growing, lots of deaths (although that seems to be almost done now). I'll be, hopefully, fishing out all remaining fry from the initial tank and moving them into a larger growout tank later this week. I'm resigned to the fact that these guys will be a long time in maturing...I'm just hoping that I can get enough of them to maturity to have a decent choice of fish for F3. I'm hopefully that an injection of new genes will allow F3 to grow a little quicker and reduce the number of deaths...
  4. Ah - I stopped heating my Fishroom because it got too expensive. I only have heaters in my tanks now. During winter, the room temp drops considerably overnight into the low teens but the tanks stay above 26C...the spawning tanks are stable at 28 all the time. My spawn tanks are only 20L tanks and I use 50W heaters in them along the back wall. Are your heaters thermostatically controlled or hard coded to a set temp?
  5. Welcome Paul. Any reason for turning the heater off overnight?
  6. Hi Morgan I like the idea of shrimp in a small planted tank somewhere in the kitchen or lounge...maybe one day Welcome back!

    So now you're looking for plakats with the best webbing reduction in all three unpaired fins, in the colours you want, and possibly without any red wash... So not pic 1 or 2, but yes to the top fish in pic 3 and the girl in pic 4, although I've found if you leave the girls a little bit longer, their anal fin will start to extend noticeable past the square look if they are long or mid fin carriers. I'm also considering pairing all my F2 keepers with a DTPK to introduce a broader base dorsal and additional rays in all unpaired fins, even though I don't have DTCTPK...yet (next year this project will begin in earnest). Got pics of male plakats hiding in the spawn?

    Yeah - I'm late again...and still haven't got around to doing photos... F2 - 20140902a - Recessive Line - week 9 Mr Big: 1.7cm Average: 1.0cm Runts: 0.6cm (still over it) F1 - 20140902b - White DTHMPK Line - week 9 I've finally split these guys and they are much happier for it. Mr Big: 1.8cm Average: 1.4cm Runts 0.8cm I have finished off the winter Black Orchids, having jarred 7 additional females for consideration before picking my F2 keepers. I've kept 2 males for consideration as well. All are individually jarred now and being allowed to mature further before I make final choices. This has freed up two grow-out tanks. I'll be doing big water changes on them, cleaning them up a bit, and then moving one lot from 902a into one tank, and the remaining fry from 902b into the other one, so all the DT's will be in bigger accommodation, a third of the CTPK's will be in bigger digs, and the remainder can be split between numerous smaller tanks. All up, the two spawns still amount to around 300 fry but once the moves are done, they should be spread across 6 tanks. Planning on doing all this on Friday evening

    From the data collected so far, coupled with anecdotal reports from the Betta Radio Show and printed reports around the place, the current trends suggest a few things: 1. Long fin grow quicker than plakats 2. Dark bodies grow quicker than light bodies ...so of course I'm trying to grow out two spans of light bodied plakats and am getting frustrated at the slow growth... It seems I had two week 5's listed as well - so I'm onto week 8 now and I've updated the week numbers which were previously incorrect. Going back and looking at the calendar, these guys were all started on a Tuesday as well...so it's 8 weeks tomorrow, whereas I've been reporting on a Thursday or Friday (ish). F2 - 20140902a - Recessive Line - week 8 Big water changes over the weekend. Die offs have definitely reduced this week. I have a tank of approx. 50 and a tank of approx. 100. All the deaths have happened in the over-populated tank. Still quite a few tadpoles in that tank as well so I expect to see a few more deaths yet before things stabilise. Smaller population starting to fill out better. Mr Big: 1.2cm Average: 0.9cm Runts: 0.6cm (over it) F1 - 20140902b - White DTHMPK Line - week 8 Yep, still haven't split them...will be doing what I can to finish getting the grow out ready this week - top of the priority list. The average and the biggest seem to be levelling out so it has to be done asap. Estimates put this population around the 150 mark...maybe more as there hasn't been many deaths at all compared to the other spawn. Mr Big: 1.3cm Average: 1.1cm Runts 0.6cm (only one of these guys left - everyone else is around the average size)
  11. These guys are beginning to annoy me...much like their parents spawn did. There was a suggestion at F1 that the genes may be a little on the weak side and this seems to have carried over - next generation will be spawned with the DT spawn of the same age to try and improve both the form and the strength of the genetics carried... Have split them into two 20 litre tanks. Second tank is doing better. First tank needs a major water change I think as deaths are still occurring on a regular basis, although the numbers have reduced significantly. Still small(ish) in the first tank - growing better in the second tank.
  12. These guys a puttering along - most people are aware of my slow growth rates by now... Unfortunately, the biggest fry decided he preferred the view lying on his side on the bottom of the tank, and promptly keeled over not long after I noticed him - not happy. I've not had many deaths with this spawn, so to suddenly lose the biggest was unexpected and extremely annoying! Still haven't split the spawn into separate tanks - must do it soon... Still aren't interested in grated blood worm...
  13. I have about 20 of these guys still growing out - most are just about ready to be moved on like a large number of their brothers and sisters have already done so. I have a current short list of three males and four females, which I will reduce further shortly. But for all intensive purposes, this spawn is done

    Going through a bit of a demoralizing stage presently - had a couple of unexplained deaths, in different tanks...including my biggest DTHMPK fry F2 - 20140902a - Recessive Line - week 7 Second group doing quite well, starting to grow quicker. First tank is still experiencing a steady number of die-offs. Need to do a major water change I think, although the parameters seem fine. Mr Big: 1.1cm Average: 0.9cm Runts: 0.6cm (over it) F1 - 20140902b - White DTHMPK Line - week 7 Still haven't split them (smack my wrist), there's just not enough time, and the energy to make time is seriously lacking... Mr Big: 1.2cm (The big fella measured out at 1.5cm - not happy) Average: 1.0cm Runts 0.6cm

    Nice to know I'm not the only one with runts who refuse to grow F2 - 20140902a - Recessive Line - week 6 I've moved half (sorta...well at least a third...) of this spawn this week. Will try blood worm again starting next week. Mr Big: 1.1cm Average: 0.8cm Runts: 0.5cm (over it) F1 - 20140902b - White DTHMPK Line - week 6 Havent had the chance to split these guys yet. The intended grow out was going to be my plant storage tank (for plants when I'm not using them elsewhere), but the pH was way different to the spawn tank, so doing water changes to level it out, and then I'll split them (maybe Sunday - got first cricket game of the season on Saturday so it depends if I can move...) Mr Big: 1.4cm (must get a photo of this guy - the steel irids are obvious right now, but I expect the Opaque to start showing soon) Average: 0.9cm Runts 0.6cm

    Should have posted this Friday last week but a long weekend beckoned and things just seemed to slip away.... F2 - 20140902a - Recessive Line - week 5 I must move half of this spawn this week. Was intending to do it over the long weekend but never got there. They are just not growing very well. Their parents were also slow growers. The number of fry in the tank is steadily decreasing, but still plenty to choose from. Didn't want a bar of the grated blood worm. Mr Big: 1.0cm Average: 0.7cm Runts: 0.5cm F1 - 20140902b - White DTHMPK Line - week 5 Going better than the recessive spawn, but still behind the growth curve - will look to move half of these guys into bigger quarters this week. Didn't take to the grated blood worm either Mr Big: 1.2cm Average: 0.8cm Runts 0.5cm

    Jay - how many spawns have you got on the go at the moment? I'm finally trying to catchup on all the measurements. Is it three you currently have in the tank?
  19. Sounds like you need to get an alternate power source sorted for the fish room, Les. Good luck with the spawn. Should be some nice form red hmpk fry from these two...
  20. fingers xed for you this time round
  21. This is the first male jarred and wont be kept for the breeding program. The damage to the dorsal is from his sisters, or possibly the second male... This is the second male (to be jarred this weekend and hopefully I'll get a better photo). This guy is currently leading the race to be used for F3 Much more plakat looking and better webbing reduction We'll see what he looks like properly when I get him flaring...

    F2 - 20140902a - Recessive Line - week 4 Mr Big: 0.9cm (couldn't find any bigger than this last night) Average: 0.7cm Runts: 0.5cm (sorry - still blurry - camera still struggling) F1 - 20140902b - White DTHMPK Line - week 4 Mr Big: 0.9cm (no growth in the biggest here either) Average: 0.6cm Runts 0.4cm
  23. This has been the discussion so far: http://www.ausaqua.net/index.php/topic/15081-males-or-females/
  24. Thanks Paul - I'll keep that in mind. The girls are looking good, the webbing reduction is well formed on their side of the house. Fixed a lighting issue I had over the growout tank last night and had a good look at the juvies still growing out - I have a horrible feeling this spawn is once more female heavy. I spotted only a few potential males left to come out. That will make around 50-60 fish which make it to maturity from this spawn and less than half a dozen males among them.... I think I'll have to go back and have a look at the thread in the lab about spawning for gender....
