Hello everything has been going good in the 55 but the past two days the tank has gotten increasing cloudiness. I checked the parameters and nothing stuck out as an issue. My first suspect is filtration, I'm using a UGF, and the water has been perfect, and clear. The fish wrr breathing heavy yesterday but are normal today. I'm checking levels again as I type though. Another issue are the breeding convicts. They really aren't doing any physical damage but are harassing even the flowerhorn. I underestimated the evil of breeding cichlids, it has been bad but has gotten REALLY bad, I think they are about to spawn in the next 24 hours. I'm putting a divider in but the reason I'm even putting this issue in here is because the y have been digging holes in the gravel, and was wondering if that could be an issue. Thank you. PS those particles are bubbles I have bubbles coming out of powerheads for extra Oxygen
