I was wondering if there are any good snail eating fish that would work for a 20 gallon long with 6 serpae tetras and a common pleco. Or am I stuck with manual removal?
:iagree:That common pleco is going to get big, very big. I wouldn't add any more fish. Stick with manual removal, and read up on snail traps to catch them. Its usually a bad idea to add a fish to fix a problem, esp, when that fish might cause other problems.
keep your tank clean and you wont need a snail eater.
put a few livebearers in there (swordtails would be my recommendation) depending on the kind/size of the snails, they'll eat some of them.
