Synodontis Petricola breeding in all male tank

[Eugooglizer]

I have about a dozen Synodontis Petricola in my all male hap/peacock tank. I recently was cleaning one of my fluval canisters and found a baby petricola in one of the media baskets. I dropped him into my 20gal hospital tank and he is doing great.

So here is my question: is there something I can put in my all male tank to give the babies a better chance of surviving since my synos are obviously breeding? I am not looking for all of them to survive but it would be cool if a couple made it here and there. Right now there are 3 30 pound pieces of holy rock that they like to hide under.

The tank is 125 gallons with all male hap/peacocks, 2 clown loaches, a dozen synos, and 2 bristlenose. All have been together for around 3 years.

Probably lucipinnis. You could make a pile of small rocks too small for the adults.

Never bred them myself, but have friends that have. Its my understanding that the petricola will eat there own eggs. If memory serves me correctly U have to make a nest using marbles so that the eggs can fall through and not be eaten by parents.

That would be true for lucipinnis. The fish is still sold as petricola, so many are still calling them by that name.
