mouth rot

Guppies and mosquitofish are fairly common thiamanase free fish. Try to find a local higher end aquarium store, there's at least a better chance of finding feeders in good conditions. Obviously ask to see the conditions they are stored in. Lucky for me there is a place that sells minnowfish in downtown Austin that is obsessed with cleanliness of their water (they actually buy fancy neutral ph aquarium water for all their tanks and don't even use city water at all) as well as feeding them good food.

Do you know which species?

Meant to say mosquitofish my bad.

Gambusia, good feeder.
