well I have had Tweek for a long while now, and he very very obviously has some canceres tumors. he is eating and still swimming normally, however I know that when stressed out he tends to bite and eat his tail. right now there are no outside stresses in his life. he lives alone in a 5 gallon with a heater and sponge filter. I check the water stats often. there is nothing he could snag his tail on.
I can see several new tumors growing on him, including in his abdomen, particularly when a light shows from behind him. Tweek is also not a spring chicken either, I have had him for nearly a year, and he was full grown, but emaciatedly thin when I got him. I had planned to let him live out his life until he was no longer happy and the tail biting tells me he is very stressed.
I am going to post a few pics of what the cancer looks like, but honestly I think I should put him down, I don't want to see him any more in pain or discomfort.

He's so gorgeous and I remember when you got him. So difficult to let them go but you know what's best for your little guy.
