Instead of a RTS, I would look at adding 4 more corries to your tank, they are schooling fish and enjoy being in groups of atleast 6
I agree completely. A Red Tail Shark should be in no smaller then a 4 foot long tank. They also can be aggressive with tank mates though that varies from individual to individual. I too would add more of the Cory's. I find them to be so fascinating, I wish I could get some but I have a Rainbow Shark and don't want dead Cory's.
