Help, missing cories!
Hey, just bought four julii cories last night. The count was at four this morning, four this afternoon, and then...
3 cories at 3:30 pm
2 cories at 6:40 pm
I don't know what's going on, but I can't find them. There are no bodies, and no bad smell, so I'm hopeful they aren't dead.
I literally turned the whole tank apart this afternoon looking for Ed, the first missing cory. I took the filter apart three times, and moved the heater out just in case he got stuck, and nothing. And now, two are missing. I took the big plastic centerpiece that looks like driftwood and stuck my hand in to check if they were stuck in there. I dug through the gravel to see if they were buried, and nothing. I checked a seven foot radius around the tank to see if they somehow jumped out because they're very active, nothing.
There's nothing in the tank that could eat them. It's just cories and tetras, not even a betta in there.
Am I missing something (except for the cories)? Is there something cories can do that I don't know about that makes them good at hiding? Are they capable of burying in the gravel (it's rounded, no sharp edges), and popping back up later? I'm really hopeful they'll turn up, but has this ever happened to anyone else?
If they're dead, what are my options so the remaining two aren't lonely? There are no more julii cories for sale in my county so replacing them isn't an option. The only store that sells them won't sell them for a while since the four I bought were the only ones available for months and no one was buying them. Would they be ok with some other type of cory (albino, peppered, emerald, etc)?
Thanks for reading this. Sorry it's a bit long.
