Horrible Disease Causing Heammoraging

[KerriPaul]

Some of my danios have gone down with a horrible disease that causes patches of blood, no swelling like dropsy though. The haemmoraging is on body and fins.

This one in the photo was one of the wosrt affected. The symptoms appeared overnight View attachment 32237View attachment 32237

Looks like septicemia to me, wha are your recent ammonia, nitrite and nitrate stats? How often and how do you go about tank maintanence on average? How long have you had the danios?

 

[KerriPaul]

The nitrate levels were quite high as I hadnt changed the water for 2-3 weeks due to courses of anti white spot and anti blue green algae remover.

They have had three large changes with fresh rainwater over the last week and nitrate is down to 10 ppm so hopefully it will fade away.

How on earth does septacemia get into the tank?

The danio concerned is about 18 months to 2 years old I would guess, some younger ones have also gone down.

I normally change 20% weekly of water and have two massive filters with bio chem zorb and lots of plants.

Looks like septicemia to me, not the writer of this in formation below.

Septicemia



Symptoms:

Fish may have reddening at fin bases, blood streaks throughout the fins and body, small hemorrhages around the eyes. Dull listless behavior and lack of appetite may also be present.



Cause:

Systemic bacterial infection caused by various bacteria, including Aeromonas, Pseudomonas and Vibrio. The illness is often brought on by poor water quality or as a result of parasitic infestations or other infections. These bacteria enter the blood stream and circulate through the tissues causing inflammation and damage. Inflamed blood vessels in the skin and at fin bases stand out. Blood vessel and heart tissue damage cause hemorrhaging and consequently leakage of body fluids into the abdomen, which may lead to Dropsy.



Treatment:

Water conditions must be improved for all fish in the tank, regardless of how many fish are infected. Check your water’s Treat with Kanacyn or Tetracycline as well as with a medicated food if the fish will eat. If parasites are suspected, all the fish in the tank should be treated with antiparasitic medication. Using salt to help restore osmotic balance might be helpful.

Thanks Wilder,

Theyve had massive water changes, one heaped teaspoon salt per 4 gallons and a large dose of melafix so fingers crossed.

I had an angelfish go into spawning mode and attack about 40 of my danios taking lumps out of fins, and otherwise injuring them - one lost an eye - before I realised the culprit, so I suspect that is the root cause

Sorry, don't you just love fish at times, good luck.

Hate to say this, but salt is not very good on danios and may further irretate the condition, i would just stick to the water changes and melafix- take care not to take out too much water during the water changes and to make sure that the new water is as close as posible in temp to the water in the tank, the nitrate levels should be ok as long as they are not over 40. Septicemia is often brought on by stress so just try and keep their enviroment as stress-free as posible, keeping the tank lights off for longer periods of time will also help lower stress levels .

 

[KerriPaul]

Many thanks,

Too late now with the salt but will bear it in mind.

If its stress related I would say being terrrorised by a large angelfish has a lot to do with it. Water was matched as much as possible but there is an inevitable drop pending the heater rectifying it. That should not be a massive problem for danios as they are used to that in their natural environment when the rains come and run off the himalays - usually induces spawning.
