I read that they are beginner level and are easy to care for, however I have had a few and no matter what I do, they end up dying. I love plecos. They are interesting creatures, but I just don't know what I'm doing wrong for these little guys. I have a 90gal tank and I am interested in the plecos that grow to about 6". Not the common one's in the LFS that get 12"-18". I have put driftwood in the tank, I feed them algae wafers, keep the water temp at 80F, give them hiding places, water parameters are all good.... plecos can get expensive and I don't want to buy another one just to watch him die. What am I missing???? All the other fish in the tank do just fine.
