Exodons in a 50 gallon with an Eheim 2215 and Odyssea HOB rated for 50 gallons? I know that some prefer the overstocked look and others the 1 sq. in per gallon and the minimum of 10 fish. I just want what ever is reasonable because they run for about $8 a piece around here. I've looked through some of the threads on Exodons and haven't really been able to judge how many are capable of going into this size of a tank. Any feedback would be helpful. Thanks
