Hi i have a 60 gallon tank thatI had baby p.bass in but they had a bad batch of feeders and akk died off except one which is in a hospital tank. I'm going to take a break off p.bass until i have a little more knowledge about them and until i] have a tank to put them i when they get bigger. So what should I put in this 60 gallon? I dont want a planted tank so what else
