Lazy Bronze Corys

[drfu]

I have had my 3 bronze corys for about 3 months now, when i first got them they seemed to love to swim around jumping to the top for air, overall quite entertaining! Now they seem just live @ the botton, like to eat a lot, gotten a bit fatter since i got them. Is their perhaps something wrong with them?

Tankmates, clown loach, 2 Chinese algae eaters, 2 otos, 5 blackskirt tetras.

Tank: 33 gallon tank w/fluval 205 & surface skimmer, aquaclear 50, lots of live plants w/sand & gravel substrate.

Parameters: no detectable ammonia, nitrites, copper. phosphates are between 1-2 ppm. Ph is 7.7 nitrates @ 40 ppm but today is water change day, temp is 76

Hi, doesn't sound too drastic. Maybe they are eating too much(?) but they sound well.

Keep a look out for the CAE trying to attack your Cory's there's a thread on here about some owning having Cory's and there eyes going missing and it turns out it was the CAE

Very interesting about my cae, i know one is the dominant one vs the other but i have not seen them be aggressive towards anyone else. I have seen one of them share the same hideout under the same log but will keep an eye out. I am slowly dropping my temp down to 73 from 76. My next step is adding more o2 to the system.
