I have a 29 gallon tank. I am going to put in one convict and probally one firemouth. I am gona put them both in at a young age at the same time. I was wondering what are some smaller schooling fish that can go in the tank. They could act as deithers and targets plus fill up some space and add more life expecially if they will swim in the upper regions of the tank also. I know one might get ate once in awile but i will introduce them at the same time to let them start off together. I was thinking tigar barbs or something if any one can help out with advice i would appreciate it thanks.
