Has anyone else experianced problems with their Cories? and Dirt..

the only problems i've ever had was from the cap causing the barbels to wear away.

Are the substrate granules small? Maybe their ingesting it and its stopping up their systems. Some fish that were raised around gravel and then moved to sand can ingest it thinking its ok. Just a guess.

I don't think it's your water quality. Kuhli loaches are very fragile IME, they'd be the first to go if there was something wrong with your water. I would look at the substrate to see if anything there is being ingested as Zoea suggested.

UMMM, well its the NEW ones that I add..I have 3 or the original 6 and they are fine, its just always the new ones I add that last only a couple of days.

Yes there is SOME "bark" mulch on the floor towards the back of the tank but they are big pieces. It really drive me crazy cause I want several cories, but I hate adding them just to see them die.

I also might look into another variety.

Hmm well any new fish you get should be quarantined separately for around a month before adding. It's likely they could already come to you sick/diseased, and that can spread to the other fish in your tank. I dont have any experience with dirt so can't help ya with that
