Dead Harley.....possibly Further Damage From Mini Cycle

[hollyp0p]

I lost a harley a week or so ago to stress form the mini cycle in my QT tank, I fear another one may be suffering due to the same thing, I can't move them to my main tank though for fear of it being anything contagious that will spread to my other fish.

The harley today seemed almost like one side has been maybe eaten away, it's swollen, when I got it to have a better look it looked like there was internal bleeding, and I think damaged tissue hanging off the affected area, since observing the redness went down, so I decided not to cull, put it back with the other harleys, I've done a 70% water change and added myxazin and pimafix with the intention of keeping an eye on the fish, if it gets any worse I shall euthanise, as I'm sure internal bleeding's not good!

just fished him out it looked dead, it's got a tiny bit of movement but I'll have to euthanise, it's clearly unwell.....will get a photo incase it's anything I need to worry about for the remaining harleys!

Right the deed is done, as you can see from this photo I discovered the harley had a definate air bubble under the skin, very visible, it's also very pink (where it was very red when i first saw it)

Is this as I suspect and damage maybe from ammonia burns or just the stress of the mini cycle in my QT tank, or could this be something else?

R.I.P.
The sores look bad.
Air bubbles beneath the skin is gas bubble desease.
Is your airstone to powerful.

yeah i think he'd lost his scales all along that patch poor thing!
I am only running the fluval 1, no airstone....I was wanting to move them today to the main tank, do you think it's safe to?

 

[WILDER]

If water stats are fine yes I would.
Match temp and ph.
Strange about the bubbles beneath the skin then, as that usually gas bubble desease.
Get you some info.

Gas Bubble Disease is a result of supersaturation (excess levels) of the water with the gas, nitrogen. Supersaturation occurs whenever the pressure of a gas in the water is higher than the pressure of the same gas in the surrounding atmosphere. When there is this difference between gas pressures, the gas gets pulled too quickly out of the bloodstream, leaving gas bubbles behind. This is what happens to SCUBA divers who ascend too quickly and create a big difference in gas pressures, which leads to the diver getting gas bubble formation or the “bends”. In fish, gas bubbles can accumulate behind the eye, making it bulge outward.

Water in a newly filled tank will be supersaturated with gases and you will see the gas bubbles covering the inside of the tank. The more that the water is agitated as you are pouring it in for the first time, the less supersaturation you will have. Agitation of water releases gas from it. Normal aeration will speed up the time that it takes for this excess gas to leave the water. When the bubbles on the tank disappear, then it is safe to put your fish into the new water.

High-powered powerheads, that shoot streams of air into your tank’s water, can lead to nitrogen supersaturation. Treatment in this circumstance would be to turn down the powerhead water stream adjustment to its’ lowest setting and allow the air pump to be the only source of air. For the next few days, observe your fish. If the pop-eye starts to go away, then it was due to nitrogen supersaturation. If there is no change or the condition worsens, then the pop-eye is most likely due to an infectious cause and probably a bacterial one.

An excess of nitrogen gas can also occur as a result of a large build-up of nitrites and nitrates in the water and has been seen in deep wells and frozen-over ponds and lakes, but probably does not happen to a significant degree in the aquarium. It is always important however to maintain excellent water quality for your fish. Under normal circumstances, there should be no measurable nitrites and the nitrates should be kept at 20 ppm or lower for all but the most sensitive species.

Ah yeah that is a bit weird I think he may have been the harley that was nearly lost before, it obviously did him so bad damage that just came to light yesterday.
I'm going to check water stats and do a water change in the main tank a bit later, then they can go in there......but now I need to find 3 more harleys to make it up to 6 and not 2, poor little things!

Harley are very sensitive to water quality.
Good luck with the new fish.

sooner i move them the better then as the main tank's very stable and consistent, they'll be happier there, especially once I've got them some new friends, hoping maidenhead still have pitbull plecos in too, was going to get another one at the same time

 

[WILDER]

Good luck with the pitbull plecs as mine all died.

awwww yeah i remember you saying....internal parasites?
Mine's been good since being the starter of all my worldly problems in the tank.....luckily for him i still think he's awesome, and i think he'd be much happier with a friend
