The biggest is about 4 1/2" , 4", and 3". I have had them in a 25 gallon for three years and then this tank. So they are about 4 1/2 years old.
The male goes back and forth between females and pumps out the fry. In a year between both females I have seen 5 or 6 swarms of fry. Out of all them 3 have made it through the jungle. So 6 Convicts total>
.... Funny seeing two convicts with fry on one side of a 220 gallon aquarium holding all the other 19 fish to the other side of the tank... Yup they can be tough...
