I have a 55 gal with plenty of rocks in it. I originally bought 12 demasoni and 6 yellow labs. Now I have over 30 demasoni and 6 yellow labs. The demasoni range from full grown (3-4+ inches) to small fry. Will my demasoni population continue breeding? Will the numbers level off? Can my tank handle so many fish? I have an AQ500, AQ300, powerhead w/ filter, and I vacuum the sand and change 30% of the water weekly.

in a 55 i'd keep the numbers down on the demasoni to 12-15 maybe, a 75 would be better, any fish that you get from spawns i would probably take out. doesn't hurt to have another tank to raise up the fry either if you ever lose your originals.

They will continue to breed. If you only have Demasoni and labs in there, 20 or more Demasoni is not terrible.

Get 3-5 Synodontis Multipunctatus for fry control. I had Lucipinnis and still had survivors, but those Multi's are more efficient!

I had over 30 demasoni (mostly juvies) in a 55 with yellow labs. I would say at this point with juvies to not worry about it. What I would do is as you begin to identify males - remove them (I would not remove the dominant male - I would remove sub-dominant males). This would allow you to begin to have a large number of demasoni in your 55 with less aggression (if that is possible with demasoni) as most of your demasoni would be females.

A large group with lots of rock work will work and look good in your 55 if you are willing to do the tank maintanence (cleanings, water changes).

:lol:

I started out with 20 adult demasoni in a 55G. 6 months later, I sold them, and when I went to bag them to take to the new owner, I gave up counting at 75.

You should be fine with that filtration and diligent water changes.
