Hi everyone,
I'll go into details to hopefully give a clear picture of what's going on and will write a summary near the end, for those who don't want to read it all.
Around 2 weeks ago I suddenly noticed a white patch on the head of one of my BHT's. It must've appeared suddenly and not slowly grown over time, as I spend quite some time looking at my aquarium on a daily basis and I would have noticed this earlier.
This particular BHT in the picture is around 2.5 years in the tank now and is part of the older generation. It's the runt of the litter and gets bullied by the big boss BHT, who is about twice its size. I originally added 5 BHT in 2021 and 3 of them remain to this day. One was lost quite early on and the other one passed away in the end of October 2023, while I was away. My mother took care of the aquarium for me and was doing a good enough job at it. She told me when I returned that she just noticed the BHT had a white eye and it developed some fluffy, white patch on it. She thought it was fungus and didn't know what to do, so the fish passed away. (She didn't take pictures) I told this later to my LFS and the guy there said it was most likely a fungal infection from a wound. He said it was probably from hitting driftwood or a rock in the tank after some hierarchy dispute. Especially given the fact no other fish ended up getting any signs of fungus or any other health issues for that matter. But after this death the group dynamics of the BHT changed. They got skittish and shy and started having disputes over the darkest place under the driftwood. The biggest one now fully dominated the other 2, with the smallest one taking the most hits and being forced to the corner of the tank to hide under some small Amazon swords.
I decided to add 5 juvenile BHT's to restore the balance. This worked out perfectly and has also made the older BHT's less shy again. Their feeding responses are insane and they are starting to color up nicely. Of course there are still some hierarchy disputes here and there and the big guy still reigns supreme over the prime spot. But that's just the nature of these fish I guess.
Long story short: Could this spot be a wound from hitting a piece of driftwood and if so, is it infected with something? And would it need any treatment? There's no fuzziness to it, so I think a fungus is unlikely but I could be wrong. The fish is also still active, is feeding well and no other fish are suffering from anything that I can notice. I'm planning a visit to my LFS soon as well, so I will ask them too. But in my opinion, more knowledge and advice is always welcome.
Water params and cleaning routine:
0-10 mg NO3/L
0 NO2/L
GH: 7-14
KH: 6
PH: 6.8
Chlorine: 0
The tank is a Juwel Rio 180, I do weekly 25% water changes together with gravel vacuuming. I clean out the filter sponges in the tank water and replace the fine filter floss weekly. Every now and then I replace one filter sponge. When I'm refilling the tank I dose it with Tetra Aquasafe in the bucket, before adding it to the tank. I also add a small dose of beneficial bacteria after the water change to make sure they are always present in healthy numbers. Not sure if it's overkill, but I like doing it anyway.
I hope someone here can tell me more. Thanks in advance!
