Any recent changes..new fish/filters/power outages etc etc: Purchased at the auction two carbon bamboo caves and a bag of 5 CRS, added the CRS on tuesday night and the two caves last night. I suspect it was the caves but i have no idea how or why they would kill off an entire colony of healthy + happy catfish? Anyone got any ideas at all? Im fairly devistated and angry about it.
I thought it could have been the CRS or the water in the bag but i doubt it because they are fairly sensitive little buggers and they all died today too, along with half of my cherry shrimp.
Weird thing is, all the other fish in the tank are perfectly fine so far.
