i got a 48 gl with 2 angles and 2 grammy and a pleco no one fights with anyowen they all keep to them selves but i think the tank needs more fish or somthign in it beside polans and ornaments
Use this site to identify your pleco, then we can tell you if you can add more bioload to the tank. It may be fully stocked as it is, the common plecos most people seem to buy grow to 2'(way to big for your tank), while bristlenose plecs will only reach 6". Also, as TheZoo said, whats a grammy?
What's a grammy? I've seen you post that before and have no clue what kind of fish that is. If you mean to say gourami, what type of gourami? There are many different types of gourami with huge size differences and that will make a difference in what people recommend to you.
All I know is that my grammy was about 5 foot 6 inches tall and she would have been pretty crowded in a 48 gallon.
