Catfish are scaleless and he may be showing signs of burning from the meds you have used. Scaleless fish are very sensitive to meds and you can burn them if you are not careful. I would give him a dose of stress coat to sooth the skin and just let him be in some clean water and see if that does not heal the welts.

June, Thank you, thank you, thank you for giving me the correct identification. I looked it up on the web and you're right, mine looks just like russelia sarmentosa. It's funny because I don't really care for the looks of the firecracker plant (equisetiformis), except for in a large pot. I've never seen it in a nursery since I purchased it so I'm glad I found it when I did because the hummingbirds really like it. Thanks again, Annette

Well done! Looks like a text book classic. Nice shot.

Unless you are in the wide open, treeless spaces of the Plains, forget it. Redtails are highly unlikely to use such a nest site. If there is a tree within 5 miles, it will be used before a lone pole. (I've bred redtails in captivity, and study their wild nesting habits.) Sorry. Thanks for thinking of these great birds, anyway. Put up some kestral nest boxes way up on the poles, and they will be used.
