aro is close to 26 to 28 inches and flawless. 2 nigers are about 22 inches , megalodoras range from 8 to 16 inches and there are about 15 of them . before i rack my brain with prices anyone interested that has a large tank ? they are in a 500 gallon now and it would be rediculous for them to go into anything smaller especially the aro he needs a lot of room due to high activity
