Most of my concinnus' like the steelhead better than silversides, even though the steelhead doesn't smell fishy like the silversides. They don't seem to like tilapia much but they eat it so yeah, I noticed that too.

Be very careful about keeping them from biting each others' faces/heads! They can bite each others mouth area and it will most definitely get infected. That wouldn't be good at all. In fact, it can eventually be fatal. Check them out thoroughly and make sure their "lips" are coming together correctly and check for swelling. After feeding them separately, spray their faces and bodies with luke warm water or put them in water to wash off the smell. It also helps if you feed all of them well and keep them separate for a while before putting them back together. Ember smelled fish on tiny, I guarantee it. That's the only reason he would have bitten Tiny. Ember isn't acting strange, he's acting like a typical concinnus at feeding time. Concinnus babies get crazy over fish and will fight! Ember shouldn't have been given a chance to charge at any of the other snakes because they shouldn't be together at all when they are still in feeding mode. I'm not telling you this to come down on you or make you feel bad, I'm telling you this to protect your babies.

Again, check their mouths from the underside of their heads and look for "lips" that don't seal tightly. If you see that, be honest and come back and tell me. The earlier you catch it and treat it, the better chances of healing it up before it becomes terminal. I have had it happen to my babies too. If caught early it is treatable in most cases.
