Aren't they scissors? Scissortail tetras I believe ~~waterdrop~~
Yeah, am I remembering right that although one of the common names is scissortail tetras that they are really a type of rasbora, people seem to divide 50/50 between calling them tetras and rasboras and I've personally never tracked down the scientific name as there have always seemed to be a lot of conflicting ones floating around...yeah they are Scissortail Rasboras I think gets to a decent size but skinny get their name from the way their tails "snip" together
