Looks to me like it is a male veil tail. Fairly easy to care for but is often mistreated. I wouldnt ever put 1 in a tank less than 2.5g. 5 minimum is a safe bet but a 10g would be better still. Low water flow with mid to high 70s temp is good for it.
It will be in a 5g. I read that it can live with a african dwarf frog so it would just be the 2 things in there. I will have a place for the frog to hide.
