I needed an algae cleaner for my spare 10G I use for quarantine. I bought a brown pleco that the pet smart guy said was a rainbow pleco. That fish hides at all times. I decided he was lonely so I found him and moved him to the 55G tank. After a month of not seeing him I looked in and around everything and he wasn’t there. A couple of weeks later I looked again and he came out of a cave decoration. After some research I’ve decided he is not a rainbow pleco because there is no evidence that this is a real kind of pleco. It may be a rubber lip something. My wife tells me the next time I want to buy a fish to not and then just pretend that I did but it’s hiding. What. Am I doing wrong with this thing? Maybe it’s a schooling fish? It’s small could it’s youth that will grow out of this?
