Hm....Well anyway, i think the moral of the story here is don't but fish which you have absolutely no idea of what they are, don't buy fish which you have not thoroughly researched beforehand, and don't add fish to small uncycled tanks unless you know what you are doing etc.
But FBTgirl, i am curious now as to what tanks you have currently running exactly at the moment and how many gallons they are and what fish you have exactly in them and how many? We can help you make sure you do not have any potential time bomb problems in other tanks you have, so you can help avoid repeating the same mistakes. Also giving info on other stuff like how long you've had the fish plus how long the tanks have been set up etc too would be useful too.
