By no means am I an expert, I got a fresh water tank because I am a stay at home mom of one and it gives me something to care for in addition to my son (other than another baby!) I bought my pleco from petsmart, it was labeled as a spotted pleco but idk. It's super young, not even as long as my little finger. Anyways I really would like to know so I get an idea of what tank he will need, he is currently housed in a 10g with 3 guppies and an albino cory cat
