Hi im jason from melbourne, just started to really getting into nitry gritty of betta fish. I have a cold tank 140 community tank with shubunkins etc and a few bettas which enjoyed the currents and interaction. Ive got a hold of some 4bays tanks and fry tank. I had a successfull hatch with hundreda of fry. Unfortunately the tank had a live plant and got really murky and i added a couple litres of fresh water treated but all the fry ended up dead apart from 1. There were a few hunded and only 2 fry were growing alot more excelled then all the rest. I was feeding them powdered betta food, and also frozen blocks for betta and bryne shrimp. I could get a hold of any liquid food or anything else. Any ideas how it all went wrong?
