i have one of thos fished that have 2 fins for it's tail. it's head is all lumpy too. it also looks chubby. i dont know what they're called. my mom just got them cause they looked nice. anyways, it seems to be on it's side and breathing really hard. it also seems to have visible blood vessels lined along it's fins. i just changed the water the day before and used those chemicals to clean out the iron and stuff from the water. the chemical is supposed to be fish friendly.

so what's wrong with my fish?

btw. it just died. RIP


i had a 10 gallon tank full of fresh water the day before it died.
