I’m going to have to do some researching on firefish, mine will be going on a year in the tank. Always stay together and have a place under the rock they hide under. They will come out everyday when MHs are on. It’s when I feed.
but every so often they don’t come out for sometimes a week. Then pop out and will for awhile then disappear again.
im thinking they are breeding and taking care of the eggs.Don’t know their mating habits.
