I just noticed that one of my Electric Blue haps has what looks like some injuries to his scales on the right side. His pectoral fin also looks a bit ragged. It doesn't look like fin rot. I think he got it from going behind the filter or heater, I just added an aqueon filter to the tank to cycle, but I haven't gotten it going yet. Here are some pictures, it looks like he's getting bullied by the other fish: What can I do to prevent this from happening in the future? I will be moving them to the 75 soon, I just need to finish up the stand and get that aqueon filter cycled.
