Actually got rid of the Red Bellies when they hit about 3". Right now in this tank I have an African Rope Fish 10", a Senegal Bichir 8", a BGK 5-6", and some random red0minor tetras. In my 29 gallon tank I have a 4.5" Black Rhom though! I am moving tonight/over the weekend so I will try and have new pictures soon.
