Disappearing Panda Corys??

Disappearing panda corys!?? I have a 45g which ha(s)(d?) 4 honey gourami, 12 rummynose tetras, 10 cherry barbs and 10 panda corydoras. About a month ago I added 2 bolivian rams and have noticed since then that I can always find less and less of my corys. I found 2 dead 1 day last ween but otherwise haven’t actually found any of them and only see 3 the past couple days. My ammonia still isn’t registering so I don't think they’re rotting in there somewhere. I got the corys in June and had no issues until about a week after adding the rams. Is it a coincidence or is it possible the rams are somehow eating them or??? They seem peaceful when I'm watching the tank nobody fights or bothers each other. I just don’t understand how 5 corys just disappear in a peaceful community tank

 

They might have died and been picked apart by the other fish before you noticed.
I have not had good luck with panda corys. I got six and out of that bunch I have one left. It's sad to see him by himself but even more sad to watch cute little fish die for no good reason. He'll just have to pretend to be a bronze cory like the others.
Anyway, I have had fish die overnight after checking on everyone and by the morning they are basically melted and skeletonized so I can see if you didn't notice where they would just "disappear."

 

Maybe they are being bullied and are hiding more often? If you are concerned you could definitely start lifting up the decor and poking around in the foliage to see if you scare any out or find any casualties.

If it makes you feel any better I have 3 Cory’s in my tank and all but one are hiding atm.

I didnt realize it can happen that quickly!

I don't think theyre just hiding because the group tend to hang out together on the left side of the tank and theyre still there but less and less of them. There were always a couple stragglers id have to search for off doing their own thing but ive looked and looked the past 2 days and can only find 3

 

Your fishes will make short work on any dead fish carcass, so you might not even see any ammonia registering. But hopefully they are just hiding really well.
