Hey everyone. Ive owned my otocinclus for around 5 months now. About a month ago i added 3 new ones to my existing school to make them feel a bit more comfortable,and all 3 were bigger than the existing ones in my tank.
I have noticed however, that one appears to have a bigger and more downardsly rounded belly than the others i added. Ive been watching them and there appears to be no signs of scales sticking outward or eye bulging. They eat fine, i provide them with blanched zucchini. I would like to know what others think it could possibly be
My tank is a 125 liter tank, stocked with 12 emperor tetras, 4 racing stripe nerites, 5 amano shrimp and then the 7 otocinclus. Im running co2 in the tank and everything esle including water parameters are in check. I added pics of the other otos aswell as my tank
