So I have had my 33gal set up for years, about six years. It's a healthy tank with no issues, it's been that way for years now. I have guppies, cardinal tetras, rumy nose, glass cats, a few plecos, and some baby petricola catfish. Like I said, its been healty for years...
Recently I've added some new cardinal tetras, and some guppies. I also added a new piece of driftwood. I bought the driftwood used from a friend, it had not been in a tank for months...
Since adding all the new fish and this wood I have recently lost about 15-20 guppies and cardinals... Anyone have any ideas? I'm thinking its from the new fish for sure, but could it be from the wood? I've been buying from my local fish store for years and have never has an issue. Could this be some sick fish I bought?
