So my sister went over to a friend of hers that she works with because the lady got a brand new 125 gallon tank.
she came home with a sick catfish. A short google search leads us to the images of the bullhead catfish.
So this little guy, he's only maybe 4 inches long, is clamped up, had white patches, and his a pale goldish color up near his head while the rest of his body is black. his barbels look wispy and a little messed up.
I'm playing the bad guy here and saying we should euthanize him since he was received in this condition by his current owner and we don't have the space or funds to house him while he gets better and afterwards (My sister is terrible about letting go).
Since my sister is determined to help him, however, what can we do to help him?
