Is this normal for my Fish? Pics inside
 
Hi All -

long time lurker and have found tons of useful info on here.

I have a 45 gallon fresh water tank setup. Its been stable for almost 2 years now. I recently added the fish shown below, i have no idea what it is and the weird thing is that the tail is losing color? It was solid brown and now its turning white

Should I be worried and is there something I can do? The store asked me to add Aquarium salt to my freshwater for this fish.
Keep in mind, I have also been adding Melafix to treat rotting fins for my tin foil barbs.

Thx fellas
-Alan

Welcome to Fishforum.com, Brdl.:wave:

That's Scatophagus argus which is a brackish water species although adults thrive in marine conditions. You'll need a larger tank for a group of scats, marine salt and a hydrometer.:) As they mature, the salinity level should be increased gradually. My guess is your scat is already reaching adult stage and at this rate, the salinity must be increased.

Suitable tankmates would be shark catfish, archerfish (Toxotes jaculator), Monodactylus sebae and Monodactylus argenteus.

75 gallons would be the minimum for a small group of 4-5. Good luck.;)

P.S. Scats are prone to bacterial infections especially when kept in water with low salinity. Doing plenty of water changes and increasing the salinity level gradually should help.

Lupin - Thanks for identifying my fish.

So far, i have added a tbsp of salt for every 5 Gallons of freshwater.
what is a safe way to increase the salinity of the water? I dont want to add stress to the rest of my fishes.

I have tin foil barb, shark, gouramis and zebra danios.

Your thoughts on maintaining a safe schedule to increase salinity? So far, I have added 8 tbsp for a 40 gallon tank.

Alan, you have to do it in another large tank unfortunately. Your other fish will not appreciate the increasing salinity. You need a hydrometer to be able to get accurate salinity level. The amount of salt added is a matter of trial and error until you get the right salinity level.

Added information...

Melafix alone may not work on finrot. You'll need to do plenty of water changes.

Here's the information you may need for scats. I've kept them a few years back so I can only help you the best that I could. Again, a hydrometer should be set in store for this purpose.
Mid-salinity brackish water can be defined as species that can be kept successfully at anything from about SG 1.008 right up to full strength seawater at SG 1.025, but with a middling value of SG 1.010 being more than adequate for long term health. Classic examples of mid salinity brackish water fishes are scats, monos, certain archerfish such as Toxotes jaculatrix, Colombian shark catfish, and violet gobies.

EDIT:
Another information added..
Marine salt should be used when increasing the salinity for the scats, not aquarium salt. They contain buffers that will increase the pH important to brackish and marine species.
