hello! im new to this forum. i bought a 10 gallon fish and placed a black moor, a red cap o, and a ryukin fish in it. I recnetly bought a 27 gallon tank for only $25 it came with a filter, heater , air pump. ect. (= i got a steal of a deal.
But it seems as though my red cap is sick.
its fins and tail is fraying
and some of the scales are missing.
Is there anything i can do?
