A month. It was set about three weeks to get it started. I put the bio filter from my 29
gal on it to help get things started. I tested the water last week and it was at 0 for amonia. I put the fish in and no problems.
One other thing I have 3 small cichlids in my 75
gal, that were in my 29
gal, they all got along until I put them in the 75
gal. The convict and Jack dempsey constantly fought, until yesterday when the convict killed my jack. The convict was twice the size of the jack. So I bought another one today. This one is about 2 1/2 in long. The convict is about 1 1/4 in. The convict still harasses this one. The fighting turned up a notch about an hour ago. The convict lost that bout but I am pretty sure he will come back for more. You would think that they would fight with less room than with more. peacful in a 29
gal, very aggressive in a 75
gal. The fish dont seem to be fighting over an certain area of the tank. They just seem to be fighting cuz the other exists. I do realize that this size of a tank cannot possible hold all these fish at full size, but I am having an oscar tank made for me as we speak, It will be 200
gal. I will probably only put my oscar and pleco in it, with another oscar. I think it will be alright for the time being considering my oscar is only 3 1/2 in. Will the fighting stop?
