I put 15 baby guppies in 2.5 g tank. 5 have died. Their back fin is getting real narrow. Looks like they are struggling to swim. Any help would be appreciated.

Is the tank cycled? A 2.5 is to small for even one guppy so an ammonia spike is probably the cause.
 
Do you recommend I move them to another tank. My ammonia is 0.

I would definitely move them to a larger tank and do lots of water changes to keep the water clean
 
I have Victoria green
/nitromersol. "Ick remedy" will that work?

Malachite Green should work the first time, but if this comes back get some methylene for the future, its an ongoing problem once it starts. Try to stearilize the main tank completely.

This is a bad fungus disease that affects baby guppies, ive lost hundreds to it. I would go with the methylene blue in the future. Ive had the best results with that.
