I've researched this a lot over the last couple days but I'm still not sure. I got an ob peacock (my 2nd one) about 2 weeks ago and its acting strange. Its the smallest fish in the tank and upon its arrival it was bullied badly by my other ob peacock who is slightly larger and I'm pretty sure its a male. I was going to take out the new fish but the bullying stopped. Its fins got torn up pretty badly but the fish seemed to be a trooper! The new ob was acting normal after being bullied the first day or two, it would eat and swim freely. Once I noticed some thin stringy poop, definitely not regularly. The last couple days its acting very strange, hiding a lot, not swimming much. Its anus area looks puffy and its doing odd things with its mouth like shuffling motions. Its mouth also looks droopy. When I fed the fish last night the new ob came out like usual, went after the food but never ate a piece. It was kinda like it wanted to but didn't want to at the last second. I'm not sure if this fish is holding or has bloat from being stress out. It seems kinda small to be holding, not sure though. Here are some pictures of the fish.
