im not too sure as to what i will do with them. i have been keeping an eye on the sevrums fromt he first time i got into fish keeping. right now they are in a 55 gallon, keep in mind that they are all very small, the largest being about 2 inches. i am trying to get a pair of oscars to breed, but i dont think that i will have much luck. i have two little ones now, and if they dont pair, i will give one back. as far as tank size though, they have plenty of room for now. i have a jack in with the two oscars and two sevrums, and he is not growing fast at all. so i might bring the sevrums and the jack back, and stick to oscars, or possibly get an electric blue jack, although i dont know much about them yet, except that they are really pretty. anyone have any suggestions? i would like to keep my 75 gallon tank, but i think i would be willing to go bigger. i have had an oscar for over 3 years and he is only 9 inches so the 75 suites him well.
