I got 2 o. clowns and some cerith snails the other day and drip acclimated the fish for about 2 hours... they were alright for a couple days, one wasn't as active as the other and I just thought that it was just getting used to it's environment. A couple more days went by and I saw it getting caught in the skimmer. Half alive, I took it out and froze it, I figured it wouldn't make it. I just thought maybe he was just stressed or sick, wasn't too concerned.. Then the other one got caught in the skimmer a couple days after that.. Now my lawnmower blenny is doin just peachy, eatin' up all the algae it can see, and all my shrimp and other critters seem to be doin fine as well.. I checked my water parameters and everything is fine.. Trates were up at about 5ppm.. I'm doin a 25% change in a few because of my cyano problem.. Is it possible that the cyano killed the fish? Does it give off gasses or any type of toxins as a byproduct as such other bacteria do? I'm pretty perplexed as to why they died the stores fish is still alive... Any thoughts?
