Does this dollar sunfish have a problem?

This is Felix, a wild caught dollar sunfish. He's living in a top filtered 2 1/2 gallon tank alone with a plant and a gravel bottom. Temp is about 72. His water was filtered from his stream source and treated. He's been happily devouring small petshop bought crickets for 3 weeks. He's grown noticeably in that time. We've had these before and they have thrived until being transitioned back to stream life.

He's just developed this red area under his mouth. It looks inflammed but his appetite and alertness are unchanged. Is this a problem?

Water, for one thing, is too warm. These fish come from highly oxygenated water, you will need to monitor the dissolved O2 levels and that temp down.

Anything about his chin?

I thought this would be a cinch for seasoned aquariusts (asts?). Well anyway my beginner's guess is a chin scratch from the bottom gravel, that became infected. Couldn't really see the details of the injury until the pic came out.

Petsmart probably has some antibiotic. I'll try that. Thanks!

Hmm... just wondering - Why catch a wild fish, keep it for a couple weeks, and then transition it back to streamlife? No big deal, that's cool... I've had a couple wild fish. But why? LoL

Thanks for asking. What have you caught in the past?

We are cataloging the creatures ID/photographing them for a new "wildplace" web project. My niece loved the dollar sunfish so much (last one had beautiful color) that we caught another for her.

It feels pretty nice to let them go too. Imaging their buddy fish not believing anything about their trip :roll:

Doesn't anyone have an idea about the fishes problem?

Oh, I'm not really sure what they were. They were probably a type of sunfish or bluegill. I would keep them for a couple months and let me go. The only reason I asked is that I thought I was weird for doing that... guess I'm not the only one.

I cheched out the pics, but I haven't a clue what's wrong with him...

My guess is that the problem is stress related due to the high tank temp and lower O2 content. That is what I referred to in my first post. Stress in fish can lead to other problems such as the one with the sunfish. If you are not prepared to to go the extra mile and provide the proper care for the fish, let it go. All of the antibiotics and medicines in the hobby will not cure an environment incompatible with the needs of a fish. So, I guess that the answer was given you just didn't understand it.

Thanks again. What of the scratches on the chin and the redness in the photo?

I can drop the temp but the stream will soon be in the high 70's. He's a Texas fish. Do you think he's healthier in the colder water anyway?

The waters these fish come from rarely get over 70 degrees. As the temperature rises, they go deeper to cooler more oxygenated water. Like I said before, the marks could be stress related. Did you catch him wit ha hook? Might be the problem there. He may have also scraped himself trying to escape a seine or trap. Try using a slime enhancer like StressCoat. It will help withs lime production and also help to calm the fish. It's an all natural product and will not hurt the fish. Just keep an eye on the injury. Fish are very resilient.
