I have been using algae destroyer due to an overwhelming population of green hair algae. Now I've noticed that I only have two Cories left in my tank (there was five). Has anyone heard or experianced anything similar with Algae Destroyer? If it is this, then I need to take the remaining two out and put them in my 30 Gallon before its too late for them. They are acting very sluggish already.

Check the ingredients on the algaecide. Quite often, they will contain copper. If it does, that's probably what is killing the corys. Throw some carbon in the filter and do water changes on successive days.

Certainly a lot of algae destroyers are very chemically harsh on tank inhabitants, and have on occassion been known to cause casualties, which is precisely why most experienced fishkeepers will not recommend them.

The tank the cories are in needs a good cleanout. If there are remains of corpses they must be found, not only to clear up the tank and improve the water quality, but to prevent other fish from consuming a fish that may have a high concentration of chemicals in the tissues. The water will also need a significant water change, perhaps 50% and repeated within a week to two weeks.

It would be eminently logical to move the cories away from a potential problem, especially if it is chemical in origin. You pretty much have the answers yourself, and personally given the risks I would not wait for confirmation , but would have acted immediately.

Its not a good sign that the cories as far as you were concerned simply disappeared, it is better to keep a closer eye ,and a tighter reign of responsibility on your tank inhabitants .

I would seriously suggest upping the level of your cleaning routine , (something that would probably improve the algae situation anyway) and starting a conscientious regime of at least daily checks and headcounts for your fish. Its easy enough to do, especially around feeding times. Its never good practice to leave dead fish in aquaria long enough to rot or be eaten, they should be removed way before that, or your water quality will quickly descend into an uninhabitable level much the same as if you chucked an entire handful of food into the tank and left it.

You can try adding fresh carbon to the filter of the affected tank, this may help to reduce some of the toxicity.
