I'm stocking another tank and this one's a forty gallon breeder (filled up to about eight inches?) it's going to be a terrarium, with lots of plants and orchids. I don't want any frogs in the terrarium, so no need to worry about an aggressive fish. I do want to try for niger delta killifish in the terrarium. My Questions: 1. Is the eight inches of water too low? I know these species are larger killifish will this mean problems? 2. Egg care? Anyone have any experience with egg care of this species? 3. Female housing? How many can I house in a 10 gallon? Even if I can only house one, thats alright with me! Thanks!
