[RibSmasher]

Only question marks cause i don't know i have never in the last 2 years i have kept fish tested the water i have had these fish now for about a year and a half i do 50% water change every 4 weeks and clean the filter glass etc i don't know anything about testing will my fish die i don't get paid for about another week so i can't go to the fish shop.

Should be doing more maintance on your tank, once a week, plus i would take a sample of your water to the lfs and tell them to write the readings down for you.
A water change, and you must get a med straight away as whitespot can soon kill a fish, once they hang at the surface breathing heavy the parasites have done there worst and the fish don't usually make it.
Increase aeration as the meds and high temp will reduce 02 in the water, plus get temp up to 30, good luck.
Also before you add the med check instrucions carefully that you can go in with full dose with the fish you keep.
Don't forget to remove black carbon from the filter, good luck.
