I have 2 bala sharks that are losing their scales. At first I thought they were bite marks but i saw one of the scales fall off the other and I also saw one of the scales hanging loosely ready to fall off. Can anyone tell me what's wrong? There is 1 blue acara and 1 severum in with them but I know they are not the reason because they scared losing scaled before the acara and severum were added to the tank.

http://www.fishdoc.co.uk/disease/clinicalsigns.htm This may help you figure out what the problem is. If your severum and blue acara have no symptoms and you have the means you may want to separate them to hopefully avoid getting them sick.
Yours is not to question why, mine is to buy fish and die.

what size is the tank these fish are in?

what are your ammonia, nitrite and nitrate levels?

how often do you change the water? how much do you change each time?

ammonia is 0, nitrite is 0, nitrate is 20 (but i heard that nitrate isn't real dangerous) ph is 6.8. I have a 55gallon tank and I do a 25% water change once a month. I'm currently treating them with melifax, it's been 3 days but so far there hasn't been any improvements.

They need a tank of at least 6' in length. they are active swimmers.

you need to get it to about 50% weekly for water changes. 25% monthly is just not enough.

They are a schooling fish. So, you need to get several more as well.

What other fish are in there with them? They are skittish fish so the other fish will also play a role in their overall health.

i don't understand why i'd have to do a 50% water change every week when my ammonia is 0 as well as my nitrite, at least that's what i had read and been told. It's so hard to get advice because I'm being told different things and now I'm just confused lol The tank is at least 6' long and the only other fish I have with them is the blue acara and severum.

nitrate CAN be very dangerous. 20ppm is OK, but you might aim for 10 or less.

There are a lot of other things in the water, dissolved solids, waste products, and other ickies. You can't see them and they don't show up in tests for ammonia, nitrIte, and nitrAte. Your fish swim in and BREATHE the water and will appreciate clean water. (Think, would you prefer to breathe fresh air or stale, musty, smokey air?)

Water changes reduce wastes that can only be removed that way. They also replenish minerals. Your fish use minerals from the water (and so do live plants if you've got them) they need replacing.

Topping off from evaporation won't be adequate either. Wastes are not removed, and while you are replacing some mineral content, the dissolved parts in the water actually become more concentrated. (Only the water evaporates, everything else is left behind so while you are adding water, you are also adding more dissolved compounds).

And because I love to quote Sully:
Freshwater fish love fresh water (and they also NEED fresh water)
There! You have a bigger tank! Will you stop plotting my death now??

Here are a couple links, both out of the Library, which further explain what Gopi is talking about:

Sarah, a 55 gallon tank is 4 feet long, not "at least 6' long". The balas will grow to over a foot long each, quite a bit more. You've watched them cruising back and forth since you got them, do you see the future problem, when the tank is barely 4 times as long as their bodies? And the dirtiest, skankiest tank, with nitrates over 300 ppm, will still have zero ammonia and nitrites. That is normal in a cycled tank, not an ideal that means you don't need to change water yet.

As already mentioned, balas are schooling fish, and should be kept in groups of 6 or more, in a tank at least 6 feet long. They are skittish fish that will hurt themselves when they "startle" if you keep them in a pair instead of a school - the most likely reason yours are missing scales. If you don't keep them in a school and begin changing more water weekly than you are currently changing monthly, the balas will not make it to full grown status.
