Wound Or Infection?

[N0body Of The Goat]

One of the six has a bright white "pimpel" that looks as if it is immediately below the mouth. Because they move so fast, I would have to estimate it is ~1mm diameter and sticks out beyond the chin line by ~1mm.

I cannot see any other white spots on this fish, or the other four confident ones (the sixth danio hides in the tall plants most of the time still). No idea how much patience it will take, but I will try and get a decent camera shot after my delivery round today.

Initially, I wondered if it was perhaps a bit of food that missed the hole, but now I'm not so sure...

Here's the best shot I've managed to get in the last 30 minutes or so...



Which does not really show the questionable blemish in enough detail, so I will work on getting some more shots (absolute nightmare, these guys zoom around and seem to be quite agressive towards each other today).

Tank size: 240 litre
pH: 7.5
ammonia: 0
nitrite: 0
nitrate:12.5mg/l
kH: 11.2
gH: 14.5
tank temp: Raised to 27C in last 24 hours, was 26C

Fish Symptoms (include full description including lesion, color, location, fish behavior): White "pimpel" ~1mm diameter, sticking out ~1mm from just underneath mouth

Volume and Frequency of water changes: 6 imp. gallon change on Thursday, 2 days ago (first since introducing Danios 6 days ago)

Chemical Additives or Media in your tank: 200ml Tetra SafeStart added 6 days ago, 10ml Nutrafin AquaPlus (dechlorinator) added to new water added Thursday

Tank inhabitants: Pearl Danios, Rabbit Snails

Recent additions to your tank (living or decoration): Rabbit Snails added 1 day ago, "pimpel" in question was already visible

Exposure to chemicals: SafeStart, Aquaplus

 

[steve...c]

my leopard danio also had one of these after a water change, but seems to have gone now??

I must admit that another possible cause that crossed my mind was whether my first water change was the cause, either when removing old water or adding the fresh de-chlorinated tap water. I do not currently use a tube, but use a small tub to remove water and I tried to slowly add new water directly from a 3 gallon bucket...

Perhaps the flow was too strong and I cause this Danio to crash into the large bogwwod feature?

Hopefully this should be an embedded video clip from my new youtube account, using my Veho Muvi mincam... Albeit at 90 degrees!

Plenty of action involving the fish that is concerning me. I need to take another look, but I think I can now see a similar "pimple" on the fish's side, does not bode well...

I'm going to have to buy a quarantine tank tomorrow I think, to safe the Rabbit Snails from the treatment (Protozin), yes?

Edit: At the very leat, one Danio has 2 white spots (lip and right side, just behind gills) and another has 1 spot on its lip.

Does the pimple have any redness to it.

If the pimple larger than a grain of salt I would take the bacterial route.

Spots near the mouth are usually bacterial.
Has the fish been digging in the substrate.

 

[N0body Of The Goat]

Well this morning I bought a Juwel korall 60 to use as a quarantine tank. I took the blue sponge out of my Rio 240 and used in in the QT's Bio mini, along with ~54l of the Rio tank water. I ended up having to uproot most of the plants in the Rio, along with the bogwood, to catch all six Danios. I was rather panicky doing this phase, as several individuals "froze" and were hyper-ventilating in the corners of the tank.

I swiftly transferred the new patients to the QT and added ~4ml of Protozin, before wrapping a towel round the tank and then going out for lunch with the family (although I was constantly worrying I would come back to at least some dead fish. Thankfully, all six are fine, albeit they are staying down the bottom of the tank (presumeably as the open has no plant cover, whereas the base has the small piece of bogwood and two Anubias nanas secured to it).

The Rio has had a decent gravel stir-up, with debris collected in a net and thrown away. The plants have been re-introduced in a different layout, which I'm now totally not so happy with, but it will do for now! New dechlorinated water has re-filled the Rio and the heater thermostat has been raised to 29C to see if it will help the five "Yellow Antennae" and two "Chocolate Orange Spotted" Rabbit Snails (received from Des! on Friday morning) get a a bit more active...

Its hard to tell if there is any redness to the pimple, which look like tiny cotton wool balls, now on at least two of the Danios (one has two pimples)... They simply move so fast!

The LFS looked at a few more pics I took and commented that the fins looked "clamped" and reckoned it is fungal rather than Ich. Lets hope this works out!

 

[WILDER]

Also add some pimafix.
Spots and pimples can also be bacterial aswell as parasites.

 

[N0body Of The Goat]

Wilder, sorry its taken a couple of days to reply to this...

Is it safe to add Pimafix to the QT on "day 4" of the Protozin medication without a water change?

I may not need them for this infection, but increased by meds stock today so it now includes
Waterline Protozin
Waterline Myxazin
API Pimafix (looks like it has at least some overlap with Myxazin)
API Melafix (again, looks to have some overlap with Myxazin)

 

[WILDER]

You can use pimafix with protozin.

The spots sound more bacterial to me.
Any strands coming out of the spot.

 

[N0body Of The Goat]

Thanks for that, only just seen your reply... I shall go and give them their first Pimafix dose before I head off to bed.

I bought a magnifying glass today, but examining the pimples in detail is still a problem as they dash about! I shall have another go and spotting more detail...

Even though (the same two?) have pimples by their mouths, I've been encouraged by all six schooling quite regularly in the last 24 hours, not something they have done much off since arriving (one at least would always hide away).

My slight concern at the moment is that the now 19+ fry and swimming in the main tank! I just hope this infection will not attack these tiny strands with bluey-green eyes.

 

[WILDER]

If you have fry you can only half dose the meds.

 

[N0body Of The Goat]

The fry are loose in the Rio 240, whereas the parents are in the QT Korrall 60. No medication has been added to the Rio 240, which also contains Rabbit Snails; Bladder Snails; two random Ramshorn Snail babies (can only presume their eggs take 3+ weeks to hatch) plus a fair few live plants.

I'm off to the LFS for an ultra-fine mesh breeder tomorrow and then have the fun of trying to catch these ~5mm sticks with green eyes!!

In the QT tank, I swear one of the "pimpled" danios is showing signifacantly less "pimple" after 24 hours... Fingers crossed they are on the mend...

 

[WILDER]

Thanks for updating the thread.
Glad there some improvement. Keep going with the meds.

Good luck catching the fry lol.
