Plocostumus (?)

Question
Can a Plocostumus survive in a small (Less than a gallon) tank?

Answer
Absolutely positively NO.  I have one that is 22" long....I don't think that would fit in less then a gallon.

The ONLY fish that MIGHT be ok in less then a gallon, but I WOULD NOT do that to ANY fish, is a Betta fish.  They can live in small tanks, but you should research them FULLY before buying one.

Please research EVERYTHING prior to doing it. Being educated about something is your best bet in having a healthy pet.

Good luck.
