Hello all..I have two ebjd in a 75 gallon tank where they have been happily living for about 3 months. Over night last night one of the ebjd's rear half became a dark blue/black color. I want to think it is stress but he isn't being bullied and none of the other fish appear to be stressed. I will attach some pics, it is weird like the different colors are perfectly divided at its mid section. If anyone has had experience with this and has an idea of what is going on please help. BTW I just did a water test and nitrate 0 nitrite 0 ammonia 0 ph 7.5 and temp 78degrees. I do regular checks of the water parameters and nothing has changed that would cause stress. I do 25% water changes at least once a week.
