I was just in the middle of a water change and noticed this:
Noticed a tiny hole either yesterday or the day before and kinda thought he nipped it somehow....now, I'm not so sure. It also looks like the fin with the holes is curling.
Water test yesterday said: 0.25ppm Ammonia; 7.4 PH; Nitrate is 40.0ppm due to high Nitrate in our well water (hence today's water change that I'm still in the process of); and I wasn't able to do the nitrite yesterday....will do it in a moment.
Anybody have a clue what to do to take care of him and his only tankmate? (Other boy is looking his normal self.)
