VERY concerned about my Emerald Green Corys

Hi

This post has been here before, but seeing as how nothing's improved, I'd just like to get more opinions. As some of you might already know, none of my Emerald Green Corys are eating the food that they're supposed to (Top Fin's Shrimp Pellets), and instead they are SOMETIMES eating the blood worms/flakes that I feed my tetras and guppies. I've been trying to feed them the pellets for well over 5 days now, and they simply leave it disintegrating on the bottom of the tank. So far one fish has died, possibly due to hunger (they only sometimes feed on blood worms/flakes near the top of the tank). If someone knows what to do, please help! Thanks.
 
Is your temp.....like ....83-85? I can't keep those cory's either, finally figured it's the warmer water I keep for my Discus....plus a more acidic water for my Discus. Good Luck.....
 
Hmm, the water is now at 80.9, and the pH around 6.6-6.8. Is that a problem for feeding?

I feed my fish brine shrimp and blood worms... The tetras and blue rams eat the shrimp and the blood worms fall to the bottom. My coris ignore them until late in the night while I'm asleep. When I wake up there is no sign of food in the tank. I'd suggest putting some blood worms in and see if they are gone by the morning. Just feed the rest of your fish good or they will eat the worms for themselves.
 
I think I'm going to try something else - putting the pellets in a plastic plate and sinking it to the bottom of the tank. My reasoning is that because the pellets are so similar in colour to the tank's substrate, my Emerald Green Corys can't recognize them. My question is: will the plastic plate be okay under water? It won't release some kind of toxin or something? Thanks.
 
My cories prefer bloodworms as well, but are eager to eat Omega Brine Shrimp pellets as well as the Hikari sinking pellet (not the algae disk). When my Rainbows aren't paying close enough attention my cories also enjoy frozen brine shrimp.
 
Plastic shouldn't be a problem. However, I'm not sure how effective this will be. Catfish generally smell their food and don't really use sight. I think for most of them everything just looks blurry since they are nocturnal creatures who hunt for food at night.
 
I feed bio blend bottom feeder (marineland) and tetramin variety wafers (these have some sort of attractant, cause everybody goes wild over em), as well as algae wafers & shrimp pellets. Both in the morning and after the lights are out, so hopefully everyone gets a chance. I can't remember how many cories you have, but they seem to do much better in groups of 5-6 or more. I've got 8 pandas and they cruise out to feed with & push aside my loaches (yoyos, straita and 2- 5" weather), while the 2 (larger) peppered cories are much more shy and wait until everyone else is finished.
 
Well I don't think that it's a matter of having 3 or 5 corys. The 3 Emeralds that I have swim around the tank vigourously whether alone or in triplets, and I can see that they are foraging for food since they're constantly digging the tank bottom. However, I have since switched through 5(!!) different kinds of pellets - shrimp, but none of them attract the corys. The latest brand of food, from Omega, didn't work either. The corys would happen to swim past it, extend its bulbs to touch it, but leave it untouched. Sigh...the next brand will be Tetrafins variety wafers, if I can find them in my local pet store...
