Question: How cannibalistic are T. granulosa?

[sde]

Hi all,

So I am wondering how cannibalistic T. granulosa are? I have heard from some forum members that they will eat their own eggs, but would they eat their own larva?

See, I really want to breed my T. granulosa, and incase I do I want to know if it would be safe to put the larvae in the adults tank? See I have noticed that there are a LOT of little bugs in my adults tank, copepods, scuds, snails, little white worms, and other things. So it would just be easier to put the larva in the adults tank to feed on that stuff than it would be to feed them brine shrimp, daphnia, etc..

There is plenty of room for the adult and the larva, so that shouldn't be a problem.

So do any of you know if this would be ok? Or would the adults eat the larva?

Thanks! -Seth

I think mine eat many of their eggs.

Hi Seth,
they will eat their larvae too especially the very small ones. In tanks with very dense plants sometimes some larvae will survive but you can't be sure.
Your idea to raise them in a good working tank is good (there's always a lot of good larvae food), perhaps you can build a region in your tank that the adults couldn't reach or you put your adults in a different tank for a few weeks.

Yes, you were the member I was referring to when I said "I have heard from some forum member that they will eat there own eggs"

Thanks for the info and suggestions Fabian. Maybe I could install some sort of temporary divider or something.

Thanks guys! -Seth
