The guy I got mine form keeps his in tap water. He has a huge fish room though that tanks on an auto drip system. He said to keep the water clean but he said he found that before the auto drip, if he did more than 20% WC weekly, he found they stopped doing so well.
He also keeps them in a low flow tank. Just a small sponge filter trickling air. That is what I am doing now since my first attempt with high flow filters and big water changes didn't work out.
My first ones were very picky with food. I could only get them to eat frozen brine shrimp. Not a great diet if thats all they are eating. So far, my new ones are eating any flake I put in there. They also ate some bloodworms the other day.
I am toying with the idea of trying to raise some sort of insects for them. They eat a lot in the wild so I figure it would be good to try it in the aquarium. Just not sure what insects I can get that will be easy to keep and won't take over my house if they escape
