I checked him an hour ago and he was fine. Next check up, and:
ACK. I found there to be a lot of bugs on the surface of his tank, seeing as it is summer, humid and the lid was off of his tank, and the bugs were drawn to my desk lamp.
Is this tail biting, or did he blow his fins from getting angry at his buggy intruders? This doesn't look like when Frank would bite his tail, so I'm confused.
Either way, I put some of the oh so horrible blue staining medicine (the ruin-er of clothing and furniture, whoops) in there to prevent any fin rot, since I have no aquarium salt on me. I just put new, light-coloured gravel in there too! They will now be an ick greenish colour D:
Any help would be great!
