I got 4 of them but right after acclimating (one hour drip method) one of them went belly up. My lfs
doesn't have any warranty policy like big pet stores have, but they replaced it anyway. I even bought one more because it was last one. Unfortunately these two have died as well. WTF? So I am left with 3 cories and I am afraid to buy more. I also got 3 oto catfishes at the same time and they have died as well. Other fish in my tank are doing OK. Water parameters are good. No ammonia, no nitrites, ph 7.4 steady! Test my water daily, also had it tested at lfs
. Is it just a bad luck or what?
