Hi,

I seem to be posting here a lot! =)

I think my fish has velvet, and wonder if anyone has experience of this disease and can confirm whether it is this or something else.

I got a fish awhile back that was in a bad state. I was buying 6 fish from the LFS and didn't realise this one was diseased. The moment it was put in the tank it was lifeless and floated at the top of the tank. It appeared to have a whitish coating to its scales and on returning it the guy at the LFS said that it appeared to be struggling to breath through one gil.

Anyway he gave me a replacement fish from the same tank (big mistake!) The new fish seemed to be well compared to the first fish, but didn't want to eat, wasn't lively like the rest of the mbuna and just seemed 'different' despite being an mbuna. Over the period of about 6 weeks this fish deteriorated in the same way as the first fish and I had to euthanise it.

Now all the fish appear to occasionally scrape against the substrate. They do it infrequently, but when they do it appears as though they're irritated, not that they're defining territory. For instance, sometimes they'll swim across the tank bouncing 2-4 times on the substrate. But this only happens infrequently. There's no external signs, white spots etc. on these fish.

The bumblebee mbuna I have deteriorated and was sat on the substrate with clamped fins and breathing heavily. It seemed to recover for about a week and now it again looks unwell. There were no obvious external signs until now. On one side of the bumblebee there appears to be a white coating, or perhaps the scales are coming off? It doesn't look like the typical white spots that result from ich, though.

Here's a pic: -

You can faintly see the white on the 2nd brown band to the right of the fishes head. It's not easy to spot in this picture, but is definitely something that was that there before and is not on the other side of the fish.

I have learned my lesson about looking carefully at the fish I am buying, ensuring the whole tank is healthy and quarantining new fish for two weeks prior to putting them in the main tank. But I now need to deal with this issue, which I suspect will (is?) start to affect other tank inhabitants.

I suspect it may be necessary to treat the whole tank when I have a clear enough idea of what the problem is.

Any advice is greatly appreciated.

PS. A yellow lab seemed to deteriorate rapidly just as the bumblebee recovered, with similar clamped fins, panting sitting on substrate and not eating but without any obvious external signs.
 
Size of tank in gallons or litres.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate, and ph.

The problem you are describing can be many things from parasite, bacterial, bad water quality to ph shock.
Check the gills to see in there pale with excess mucas or red and inflamed.
Until we know your water stats we would be guessing.

Hi,

It's a 290 litre tank with coral sand substrate and ocean rock and 19 young mbuna. The tank has been running for a about 2 months after a lengthy fishless cycle, but I transferrred everything to a new tank, incl. filter from a 125 litre to this 209 litre about 1 month ago whilst closely monitoring water params. Water params remained OK. pH is 8, temp is 24 degrees, Am 0, Ni 0, Na < 5. About two week ago the Am was elevated about a 0.25 (the lowest reading on the api test kit) so I put in some Stress Zyme, and reduced feeding. It appeared to return to 0 in a a few hours. It happened again the other day (seemed to proceed the bumblebee deteriorating) so I cut back on feeding and retested and it was 0 again. Confused as to how and why I then found a dead fish behind the 3d background yeserday. It has been removed. People at the LFS said api test kit is notoriously inaccurate and so they tested Am & Ni both tested at 0.

Last 30% water change was on Saturday water is dechlorinated.

The bumblebee has deteriorated further and looks as though it won't be around in the next few hours. It is sat on the substrate panting very heavily, and occasionally will jerk about as if agitated. I just spotted it trying to scratch its gill on some rocks. Instead of flashing it is holding in one place and carefully rubbing against the rock.

I cannot see anything obviously wrong with its gills, but she's pushing them out so hard her gills look pink / red (this is normal isn't it?). The only external symptom is the white stuff on the one side of the body, but that is away from the gills.

Other fish seem to be flashing much more frequently, but so far the bumblebee is the only one that appears very sick.

If she's still alive on Thursday I will take her to the pet shop for them to ID the problem. Unfortunately they are closed tomorrow, and they are the only LFS who really seem to know what they are talking about.

The bumblebee is worse now and has suddenly changed colour and become very pale. Before I couldnt' see anything obviously wrong, but I have taken some more pictures which shows the fish looking very sick and possibly something up with its gills.

If I don't save this fish, then at least I'd like to know what is going on to keep the rest of the tank safe. I don't have a quarantine tank (argh!) which would have helped immensely and prevented me from introducing that original sick fish in the first place. This fish is now exhibiting exactly the same symptoms of the other two fish, which tells me that the first sick fish was the source?

Here's some pics anyway: -

To make matters worse the other fish are now picking on this sick fish.

api liquid are some of the best tests

your not using strips are you

No it's the liquid. The fish shop said they are rubbish and advised binning them and instead getting some salifert ? They said the hagen test kits also were often inaccurate. They're happy to test the water for free, so I"m sure it's not just a ploy to get me to spend more. But my kit registered the same as their kit, so I am sure it's working OK.

The bumblebee has died! Other fish are itching like crazy.

Red inflamed gills can be bad water quality, gill flukes to bacterial gillrot.
Signs of gills flukes are.
Flicking and rubbing against objects in the tank.
Laboured breathing, or gasping at the surface of the tank.
Red infamed gills, or pale gills with excess mucas.
Opaque body with excess slime.
Swimming in a jerky movement.
Erratic swimming or darting around the tank.
Sores on the body of the fish.
Spitting food out.
Sometimes weightloss.

Flukes cause bacterial infections on tops as in there hooks they carry a nasty bacteria which enter the fish bloodstream once it pierces the skin.

Wow that fits perfectly. So I need a treatment for flukes. Thanks.

Yes.
Flukes do alot of damage so you need to get treating fast.
After treatment you will need to use a bacterial med aswell.
Good luck.
