I have a 150 gallon tank with 17 electric yellows (2-3 inches in size, 3 holding right now), 12 acei's that are ranging from 2-3.5 inches, and 10 blue dophins that are 1-1.5 inches big. I just did my twice weekly 50% water change last night, and tonight when I got home I noticed this guy on the bottom of the tank. 1 Eye was gone, and it looks like he suffered considerable fin damage. Mouth wide open... Did he get into a fight and lost? This is the first acei I lost in the past few months so I thought everyone was getting along fine.
What do you think happened? (this guy below was on the bigger end of fish in the tank, probably 4th or 5th biggest out of the 13 acei)
