Help

[joanne1985]

i have a fish in my tank but i dont know what it is it small about same size as guppys and he is brown like a beige colour stomach and brown line across belly along side n then darkish brown on top and he keeps fighting with my neons.
i need help first to find out what fish he is cos he just accidentially swan in net when i got my clown loaches and i also need to fins out why they are fighting

I think this would be a good time to carefully take him back to the fish store and return him since you are not sure who he is and you didn't intend to buy him. If he is fighting with your other fish, I would return him right away.
