Cherry shrimp ghost shrimp and cray fish breed like rabbits in any fresh water set up my 5 year old went from 6-100 in a lil over 5 months. That said salt water parameters need to be near perfect match to that of wild condictions ie salt drops, temp drops,sunny months and cloudy days have all bin looked at by scientists with very lil luck

I've seen peppermint shrimp babies at a local fish store. The owner said they bred in the tank unintentionally. Might be a good species to start with even if it isn't as profitable.

I suspect it is difficult to make money at small scale. Hope you have luck. I would pay a premium for captive bred animals.

Yes I realize they're like rabbits, but a challenge never hurt.

As for the 'Profitable' comments, I didn't literally mean me making a side living on it. I more or less meant that I wanted to breed something that was popular and I wouldn't be sitting on them with no one that wanted to buy them from me...

Thanks for the links syncro....

and an up date.... I was at pieces for some pvc fittings and noticed a very small emerald crab, and as I don't own a true crab yet (hermits are shrimp!!!) and it was a juvi, I snatched it up, looks like I'll start there....
