Once in a while I will come across a picture of a public aquarium in which they will have a school of large Cichlids (same type), and in the Photo Lounge searcyb posted pictures of Shedd Aquarium that has one of those setups.
If Cichlids do indeed school, what size tank would I need to have a school of say 25 Red Devils?
