So i have a 55 gallon tank and an odd population
1 albino oscar bout 6 inches
2 bala sharks 5-6 inches
3 gold fish 3-5 inches roughly
1 silver tetra
1 common pleco 3 inches
and 1 crayfish
the bala sharks and the oscar were bought at the time and same respective size about 2 inches. bought about 2 months ago
everybody is coexisting very well the Oscar only harasses the tetra and only once in awhile till it seems to get bored.
now i know that quite shortly i am going to have a very over populate tank. my question is what size tank should i look into purchasing and still be able to ceep the fish that i have?
also any ideas about what type of filtration i should use i currently have a whisper 60 HOB
