I forgot to mention the flies look like black wasps, but they don't swarm, sting or bite. In fact they don't even have mouth parts. I have seen one or two but they pretty much stay low key.
I used to have up to 9 tanks running all full of cichlids until I got burnt out and sold em all. But months ago I got my dovii back because he was terrorizing his tank mates. Since then I been working with this larvae bin and feeding him pellets just once a week. He seems fat and healthy.
I would love to hear from any one who has tried this. If it worked or not. I can't imagin I'm the only one
