So i currently have a 100 litre tank with 7 neons, 2 baby bristlenose and 2 fighting fish in a hanger inside the tank. It's got lots of wood for the bristlenose and java fern, i can't put guppies in because the wood in the water i've been told makes the water difficult for them. I am wondering if there is anything else i can put in there that will be peaceful with the neons, the hanging tanks can also come out if need be. I saw someone had some community female bettas but i was worried they might make mince meat of my neons. Any suggestions for a hardy peaceful fish i can put in?
