This isn't really freshwater beginners, but there isn't a thread this belongs in, but please help me! Some gave my family a bucket of fish they caught from a lake, (I'm assuming it's mine, as the two species are both found in my lake, but I'm not completely sure) and there was a catfish that was still alive. I'm not sure they were even legally allowed to take it, because it's pretty small, and even if they could, there isn't much worth eating. I'd like to rescue it, and put it back in the lake, but I don't really know what to do. For now, I put it in my sink (there isn't a bigger place for it anywhere on short notice) and added some Seachem Prime, but I can't match the temperature, pH, or really anything else that you're usually supposed to do. Is there anything else I can do to help this fish until my parents get home and drive me to the lake?
