So I live in south eastern mi and this time of year we get lots and lots of fish flys, I found a few in my torts cage this am maybe 6 or so, I didn't see him eat them and I clean his tank every morning I'm home (4 days a week) my question is, if he does happen to eat some how bad is it? I assume in the wild they eat a bug every now and then so I would think it'd be safe, in short of covering his tank with screen which would block out light there's nothing I can really do. His cage now is wooden with chicken wire on top
