I'm debating if I should rescue a 6" Toadfish from a LFS. It was an unexpected item that came in with their Oscars. The store didn't know what it was until I told them. I'm not sure if I should get him though. I have no brackish tanks set up and I am not going to put it in with my Festae. I just hate knowing that it may die at the store in the wrong type of water. Should I set up a tank for the Toadfish and bring him home?
I think most of us would say "Yes." But are you totally psyched about him or will he soon be a burden? Never get a fish you aren't amazingly into because, after about three months, you will have lost at least 85% of that initial fascination. So be sure the math works out and 15% of what you like about him is enough to win your heart for good.
For the record, if he was free, I'd pick him up in a heartbeat.
