U have had corys and glowlight tetras together for about 4 mounths and have noticed in the past two weeks that my corys fins are missing. Theye are all alive but one of them looks fine. None of the tetras have ripped fins. Is it them?

How many tetras do you have in the tank? Also how big is the tank?

Are the corys and tetras the only fish in the tank?

Tetras are fin nipping. Cories don't just lose there fins for no reason.

Tetras are known fin nippers. I'd bet they've been getting at the corys fins. Rasboras are a great alternative to tetras if you want to keep a shoal in the tank.

There is something with my water that these GlowLight tetras are the only schooling fish I've been able to keep alive I've tried neon tetras Royal tetras chili rasboras and a few other rasboras and they've all died

You need to figure out what's up with your water immediately. Test the parameters.

Are you treating your water with dechlorinator when you do water changes?

Glowlights are awful for going after other fish (specifically they will murder neons even if there is enough space). I would acclimate and QT any new schools you might be thinking of, if there is something killing chilis and neons it might also kill the apistos.

Swords, vals, sags all need root tabs (they are heavy root feeders) to really thrive. (You can do a plant substrate if you prefer, but root tabs are so much easier and cheaper). Hornwort is very touchy in my experience.

I use root tabs for them but they just grow a tiny but then melt. Ive tried to use less and more root tabs. I also use recommend amount of flourish comprehension.

Do you put the swords in the ground? If so that's why they are melting. They are floating plants, not root plants

Swords are root plants?? You don't bury the crown but the roots can be buried.
