4 new albino cories, hopefully better luck

I got 4 new albino cories today! They are pretty small, maybe 1" long. Hopefully I have better luck with these than the last I bought... It seems like they don't like swimming at the bottom of the tank. They spend alot of time swimming up the glass, but not always going to the top to gulp for some air. Is this normal behavior?

Well, 2 are down, the other 2 seem like they are going down the same path...

I'm just about done with cories for a while now...

Any suggestions on replacements for cories? I was thinking bamboo shrimp or maybe even ottos. I personally don't like plecos, but could bend and get one if it were really nice...

Yeah dead, and this is my second try at cories this year, not going so well. For some reason they don't want to survive and I meticulously watch how I acclimate them and try not to stress them out...

All the other fish in my tank are doing well. It seems like the 2 that are left are gunna go, so I'm moving on to something else, unfortunately.
