I have 2 new electric blue acara cichlids. The smaller one I noticed today a weird spot on it’s head that I don’t remember seeing before. Could it possibly be something to worry about like hole in the head? I’ve never had a fish with this before so I’m not sure what to look for. Hoping it’s just a random spot or scrape and not anything bad! It’s not acting sick. Just swimming around happily. I tried to get a few pictures.
