Glowlight Tetra Unable To Swim

Hello guys. I noticed one of my Glowlight Tetras on the bottom unable to swim. I'm not sure if it's swim bladder or a missing pectoral fin. He didn't show any problematic signs yesterday during feeding. Think it's been about 5-6 hours. Thinking of euthanizing him so he doesn't have to suffer anymore. Thoughts?

 

Poor guy they sure are cool but my glofish don't seem as hardy as the non glofish

 

What are the parameters?
Cycled aquarium correct?

If everything checks out, I think it's best to euthanize.

 

Parameters were good. 0,0,20-30. Just did 50-60% water change two days ago

 

Could be dropsy....... glolights are genetically enhanced so they may have a weakened immune system.

 

Well, I say euthanize him.

 

Thank you. I went ahead and did the clove oil treatment. Hopefully it's not dropsy. I am starting to think it may have been an injury due to the spider wood I just put in about a week ago. Not sure but just thinking maybe during feeding it bumped into it. Kinda like joeys arrowana but on a much smaller scale.

Will keep an eye on the rest of them to make sure it's not dropsy.

You're thinking of glofish. Glowlight tetras are natural.
