I was thinking nerite but wasn't sure. I haven't had any experience with these snails. All I know is that they keep the glass real clean and can't breed in a fw aquarium. Does anyone know where some are available in America?
how large is your tank and what other algae eaters does it house?
The example for Oliver's tank I used I can only see nerites as the algae cleaning preference and there doesn't seem to be very many. Oh well... more questions to ask him when he comes here to texas =).
The snails are indeed Neritina natalensis. They do breed in fresh water. The ones that don't are N. reclivata, a brackish snail native to Florida. Everyone seems to have them in Canada, but they are apparently quite difficult to obtain in the US. I'm still working on it myself...
Sorry for the late reply, but it was CNY and the computer decided to take a break and threw a tantrum ... LOL
Am back now, the tank is a 20 gal long. It didn't house any other algae eaters but the 2 snails for at least 6 months, they did quite well by themselves but poop a lot. I recently added 2 ottos, a pair of Yamatos and a SAE.
They all get along fine with the 7 baby Pristellas and a pair of Rosey Barbs I have in that tank. It is a mismatch tank, as you can see by its inhabitants.
