Hi! I have a 20g long that I'm setting up as a planted tank with pressurized co2, but have the itch to try some nano fish breeding also. I've previously been successful breeding guppies, endlers, shrimp, and rainbows in other non co2 tanks. I've had guppies also in a co2 tank, but the fry never survived, I think due to the co2. I'm sure there are limitations that fry impose concerning water quality and co2/o2 content, and possibly micro nutrients (myth?). I'm thinking white clouds, chili rasboras, basically anything that is appropriate for that tank size. I'm thinking medium lighting, or maybe a tad less, florin volcanit substrate, other Parameters hard/soft, cool/tropical are up for grabs depending on the fish selected.
Any suggestions as to what "co2 tolerant" species to try, or that you've had success breeding in a co2 tank?
