About 3 months ago I tore down my 180 gal 6 foot tank (mostly lace rock and cichlid-black and white sand) in the attempt to capture some "cockroaches" i.e. pseudotropheus crabro fry.

Naturally this disturbed all the other inhabitants (Polleni, breeding group of venustus, 3 large silver dollars, pair of golden saums, breeding pair of convicts and naturally the parents of the offending fry).

I didn't pay attention to the female crabro enough and she began holding shortly after the tank disruption...it's been two months since I moved her to a different tank (125 gal), but she spit a mouthful of fry (50+) into the 180 before I removed her.

I counted 16 half-inchers a week ago-all of whom are now brazenly swimming among the other fish. THEY ARE NOT BEING EATEN!

I don't want to empty the tank of decor and spend way too much time thrashing about trying to catch and remove the little turds. I tried a "minnow trap" w/ brine shrimp in the bottom 5 days ago and not a single fry has been stuck!

I need a solution, and I think the solution is to add another fish to the mix. One that will eat the little fry but not take out the other fish (smallest is 1.5-2 inch convict female-well if she gets eaten she can easily be replaced...she's a convict...odds are good her and her mate will team up against the new fish to avoid being eaten...right?).

So the question is:

What piscivore will go well in the established tank ( not beat the crap out of the larger/older fish) and actually eat the rogue fry?
 
get a oscer and when his job is done eaten the fry take him back to the lfs before he gets to big to bother yuor other fish get some credit for him when you have this problem agin go back with your credit get anthor small oscer.
 
I use an adult leaf fish (about 4 inches) to keep younguns under control. Don't know how well this fish would mix with your stock, tho.

A Ctenopoma would be good in this mix, but it does get to six inches.

Ctenopoma acutirostre?

Are they able to hold their own w/ larger (6-9 inch) fish? And have you had experience w/ this fish being a fry eater?

the picture of the fish on your icon looks cool. what kind of fish is that?

Copadichromis azureus, 5 inch male 1.5 years (or so) old.

Kapiolani, what fry eater should I get to solve my fry problem?
 
That depends. Do the fry ever come out? Near the surface?
 
any kind of catfish that gets 6" should eat them right up. pictus cat wood cat just make sure its not gonna get to big.
 
Oscars are two slow, get some Crenicichla, preferably some dwarfs, although many of the Saxatilis pike species will do perfectly. The Lugubris pikes get too large and might eat your other fish as well...haha
