Silver Shark (Bala I Think) With Red Blood? On Fins

[Shaddex]

Over the past few days 1 of my silver sharks, aka BOB, has developed red area on its fins.

Pic of BOB and test results below.

Test results are a little off due to flash.

ph 7
Ammonia looking to be 1.0ppm
nitrite 0.25ppm
nitrate 40ppm

Any advise greatly appreciated.

Hey I can't really comment on the red parts but if there is nitrite and ammonia present in the tank I'd strongly recommend doing a water change ASAP so you can bring this to 0. Is the tank new out of cycling or?

Adleast by getting rid of the ammonia, nitrite and nitrate if the shark has got medical problems you are giving it the best water conditions possible someone will be along soon to comment on red no doubt

What size is the tank etc? Has it been fully cycled?

red streaks? possibly the start of finrot?

 

[Shaddex]

tank fully cycled for about 4 months.

tank fully cycled for about 4 months.

That's weird getting the ammonia and nitrite appearing after that length of time especially if nothing has changed in the tank I'd do the water change and see how he goes really we need to know what it is so you can treat.

Anyone with anymore suggestions!?

So ammonia and nitrite should stay low always ?
I thought the nitrogen cycle was ammonia increase, nitrite increase ammonia drops, then nitrite drops and nitrate increase which indicates partial change of water ?

Nitrogen Cycle

correct, but the cycle should remove ammonia and nitrite quickly enough for you to have 'zero' readings on a test kit. That doesn't mean they are absoloute zero as there will always be traces of both but not enough to register on the kits.

to be honest, a picture of the vials will never be as good as using your own eyes as we may see false colours due to camera, computer screen etc.

+1 readings shouldn't really appear on test kits as they are usualy processed quickly. Water change and monitor the readings and if they increase
Combat with water change eventually the tank should sort itself out and read
0 ammonia and 0 nitrite at random tests etc
