hey all, I was just wondering if my 20 gallon was oerstocked it has 7 guppies, 5 Zebra danios and a inch long brislenose catfish? and is filtered by a fluval plus 3. thanx :idea:
Not at all. The bristlenose will max out at 5" and the guppies and danios will never surpass 2". You have a good balance, I'd leave it like it is as you are almost guarenteed more guppies in the next few months.
