I have a tank that housed two pairs of fundlupanchax gardeneri gardeneri at one time. They haven't been in that tank for at least 9-10 month maybe a year. I've pulled 2-3 rounds of fry out and I am still finding new ones every few weeks. It's only 1-3 at a time. How long could this continue. I have never seen any killie eggs in this tank but I've never looked there is a solid layer of long strand sphagnum peat moss across the bottom so I have assumed that's where they are hiding. I've had cories in the tank since about two months after the Killies came out.
