All,

Any help would be great. I have a small eclipse in my office, the 12 galllon one. I currently have a Beta, some live plants and 2 of the small spotted cory cats. Not going into all the details, but I change 3 gallons of water twice a week (tue and fr). The ammonia=0 and nitrites=0, Nitrates at the lowest reading on the test kit. Temp 78.5.

First off the beta looks awesome and growing like a weed. He has the longest and cleaniest fins I have ever seen on a male beta. I also have a small colony of the little black snails, something is keeping them in kinda check (the beta might be eatting them for all I know), but they are breeding as I see tiny ones and some bigger ones.

My problem is with the spotted cory cats. They keep dying on me. I started with 3, 2 died, bought 2 more, 1 has died and 1 looks like he will be dead by tomorrow. The other one looks pretty good and I am not sure if he is one of the new ones or the original survior. They look pretty fat and I see them foraging in the gravel for food and whatnot.

So, could the plants be hurting them? I have one amazon sword that looks great, a small piece of hornwort(sp) and about 8 Anchanas(sp). If they eat some of the plant maybe thats killing them?

The last possibility is that something in my well water is killing them. I have used my aquarium test kits and nothing has shown up for the tests I have. I am sure that my well water is safer than public water with all the fluoride, chlorine, and god knows what else they add the drinking water. Any help would be great.

My local pet store is pretty poor and the lady who works there said the little cory cats die all the time /shrug
 
Plants aren't a threat to cories, in fact, they improve water conditions and encourage the growth of infauna that the cories will consume.

How long were the cories in the tank before the first ones died? Any signs of injury or damage on the corpses? Cories tend to be fairly hardy--but it sounds like you might not be getting good stock.
 
That indicates to me that it isn't anything within your tank. The betta is doing well, and one cory is as well, so I suspect that the source is the problem. Anywhere else you could purchase fish from?
