My main tank is a 60 gallon tank with a HOB filter, heater, and an a bubbler. In it I keep 5 Taiwan reef cichlids and a gold nugget pleco. The gold nugget has been fin nipped pretty bad and it's not willing to leave its hiding spot even to eat algae wafers. So I put my pleco in a 2.5 gallon tank which I keep a betta in. I changed the water out with the water from my main tank and put the bubbler and a divider in the pleco has 2/3 of the tank. But other than that it has no other filtration and the heater is way to big to put in there. Is this setup going to last long enough for him to heal? I can change the water out every few days easy enough.
