Otocinclus care?

I agree with everyone else who has recommended that you return the CAE. He may seem ok now, but over time he will be come very aggressive and he will suck the slime coats off the other fish in the tank. Not to mention they get way too big for a 10g.

I highly recommend you take it back now also :/
It's kinda sad to put it this way, but the pet store would take it now, once it grows it can be really hard to rehome fish like that.
Also, try to be sure of what you're buying next time, haha. I had 3 of those in my 29 gal, and they only person that would take them was a lady that fed em to her turtles :/
