I'd have to agree with Lora. Herp Derp, I've bred cichlids before and it was fun, but another drawback is they simply don't produce enough to make a valid feeder colony. The amount of pairs you'd have to have to keep just a few snakes happy would be a lot of work. Just as CB wood frogs would be the perfect feeder, breeding them and raising all those tadpoles to meal size would be an absolute tonne of work.

To add to my previous posts, I do admit to cringing when people say they feed primarily frozen fish; even moreso when it's not whole-body fish. Your snakes may be living, but you're likely walking a very fine line with a nutritionally related disorder.

Lora, I think we can agree that there's a lot more wrong with captive orca's than nutrition. They are perfect example of a species that shouldn't be kept in captivity. With other piscivorous species supplementation is much more successful; be it they supplement more than just Vitamin B1.

[edit] I think the other toxic thread was BlueSirtalis that had the problem. This can be a worry for anything bought that's intended for human consumption. So often there are salts and misc. preservatives and flavors added that we don't see or think about.
