I put in Aquarium salt yesterday, the recommended amount. What is going on? I just bought the guppies (3) yesterday and noticed that one (it's black, yellow, green, and cyan) had a yellow/white lip! I'd seen a similar condition with my previous orange platy. I also have these fish in my tank;
1 black molly
2 danios
3 guppies (in all including the white-lip)
2 platys (both are behaving strange)
2 fruit tetras (yes I later found out about the dye-incident)
1 pleco
1 freshwater flounder
1 Yo-yo Botia (a.k.a Loach)
1 cory cat

How I noticed they were sick?:
1) FANCY GUPPY: was constantly opening mouth wide, yellow and white lips, brand new when it had the condition, just transported to the tank YESTERDAY
2) FANCY PLATY: was also opening mouth wide; got him 2 days ago; swimming in place under a dark bridge, next to the..
3) DOMINO PLATY: who was barely moving at all and had red gills. (the rest of the body is white with black patterns)

HELP HELP HELP!! I DON'T WANT TO LOSE ANY POOR FISH!

PLEASE NOTE: I put aquarium salt in the past few days; the recommended amount. I feed OMEGA one red fish flakes, algae wafers, and yesterday a small amount of bloodworms.

PLEASE HELP ME!!

What is your nitrate reading as its rare to have a nitrate reading of 0.
Red gills can be due to bad water quality to gill flukies.

Bleached out white lips can be columnaris false name mouth fungus.

The Nitrates show up as white on my test strip, and white = 0. I add a lot of "Prime" and those little Jungle fizzies to keep it down. I just went to the pet store I bought them from; turns out you're right and it IS mouth fungus...as for the yellow pacing, it's a characteristic of their Gold Dust Mollies...and as for the Yoyo and Plecos bleached appearance, they have slime; and as for the red-gilled Platy: it has a gill infection. But I bought Triple Sulfa which treats all of the above. Do you need any pictures of the fish, or will the sulfa clear it up no questions asked?

Test strip are not that accurate liquid test kits are the best.
Take a sample of your water to the lfs and tell them to write the readings down for you.

Sounds like you might have flukes with the red gills, bleached out body and excess slime.
Any flicking and rubbing or laboured breathing.
Flukes also cause bacterial infections.

I'll get some. My yellow Molly died yesterday. And yes, the breathing and tired swimming, and also resting on the bottom for the red-gilled Platy; but as for the Guppy, he's very active! And is eating well, seems happy; I used the triple-sulfa because I couldn't find Melafix, it cures mouth fungus, but there's no signs of it going away. I am doing another dosage today. Ammonia is remaining so high! It raised to .25! Isn't that too high for my fish???! Any advice? I ran out of Jungle Fizzies and Prime's not helping much.

Ammonia reading should be 0 so keep up with water changes and increase aeration.
If you have to preform a water change just add the correct amount of med back to the water removed.

If you think your fish has flukes you are better off treating the flukes first.

Did you cycle the tank before putting all the fish in it?
Cycling = adding ammonia (usually over several weeks) or adding used filter media from an established tank in order to give the filter a chance to build up a colony of bacteria that process ammonia into nitrite into nitrate. Lots of pinned topics at the start of the newbie forum.

How big is your tank? What sort of pleco? Commons end up a foot long easily and need huge tanks.
