I have 2 big plectos about a foot in length each. The aquarium is only about 30 - 40 gallons. I can't remember when I got them but I think I've had them for over 2 years. They seem healthy but their space is way to small. They knock decorations over, push each other out of the way to fight for territory, and they produce poops over twice their length that wraps around everything and gets all gross. And they constantly seem to be pooping. The algae wafers are not enough. Every time I put in flakes for my other fish, they rise to the top and suck in a lot of the food. I tried putting a fresh cucumber in once and they didn't seem interested in it. I just cannot keep up with the water changes and go through too many filters. I don't really want a bigger tank because I hardly got room for the one I have. So I'm thinking to most humane thing to do is wait for someone that wants them for free. I don't like seeing them in a tank that is small for them. Anyone want them free of charge? I'm in Upper MI in the Delta County area and would even travel up to about an hour to drop them off or meet just so they go to a good home. Again I don't want anything in return except that the fish go to a good tank. My local pet store closed and I don't feel comfortable giving them to walmart. Otherwise how do I get rid of these beasts? I'm thinking craigs list next. Thanks
