I've kept a tank full of tropical fish on and off for the last 10 years. Recently I set up a new 400L tank and got some Red Line Endlers as starter fish to test the waters, so to speak.
Since then I have fully stocked my tank with community fish and the Endlers have been breeding like crazy. To get rid of my extras I asked the LFS if the would like them, expecting to get at most $1 each. I was fairly surprised when they gave me around $3 a fish. Especially for something so easy to breed as Endlers.
Since then I have set up another tank with a couple Gold Leopard Endlers to see
