Hi, i'm new and i have a few questions. Im thinking about getting a plecostomus for my 30 gallon tank. I've had the tank for about two weeks now and i see algae growth on fake plants. Brown algae. Anyway, i upgraded from a 10 gallon to what i have now. Since that time i've gone through two plecos. They died usually within a month. (I don't want this guy to die the same way) Now i know about problems with the nitrogen cylcle ect. but is it too early to add him/her? And if i do and i get those "algae wafers" How often should i feed the little bugger? (I plan to buy a small one) P.S. If you are wondering i have goldfish but since this new tank came with a heater, i can keep it at a constant temp. which is comfortable for everyone. I have accepted the risk of growing a giant 1000000 foot catfish turd suck the slime coating from my fish. They never did last time.
