Red Devil;3227591; said:you can make the 75 brackish,...they are still young.. but if you see any changes in their skin/scale color it will indicate they need to be in brackish or you will lose them to skin disease...
I can't make the 75g brackish because there is an 8 inch plecostomus, 3 inch 4-line pimelodus, and a 2.5 inch spotted pictus catfish
