1~What type of fish is afflicted?
20 days ago I noticed one or two of my neon tetras was looking bad.
1) White lump on his mouth (another one has this too, but his tails is just fine)
2) Damaged tail (his looks the worst, like a chunk of it was bitten or something. A few other neons have some damage but I think maybe it's from fin nipping - no white stuff on them)
3) White color on his "small fin" (sorry, I do not know the name). A few others have it for some time now
4) His eye looks white. Other have this too
Symptoms 3 and 4 a few have it for months now. 1 and 2 are new and I'm worried.
I ended up isolating the two affected fish to a hospital tank and treating them with neomycin (active ingredient of Seachem NeoPlex) and acriflavine for seven days. Since I live on Brazil, I have limited access to the more common medications out there.
The white lump on the mouth did not resolve, but the damaged tail improved greatly (almost 100% healed) and the eye a little bit.
Today I was taking a closer look at them and problems 1, 3 and 4 continue. They are still eating and behaving normally, though. The other fish seem totally unaffected.
Should I just keep with more regular water changes and try to regulate the temperature better? How important is vacuum cleaning under decorations/fake plant even if it stress the hell out of the fish?
2~What are your tank parameters (ammonia, nitrites, nitrates, temp, pH)?
Ammonia: Zero
Nitrites: Zero
Nitrates: aroun 10
Temp: 28 ºC / 82 º F to 30 ºC / 86 ºF
I live in a very hot city, so very hot days can get up to 33 ºC / 93 ºC outside. Running A/C all the time on the room is not a possibility due to the costs.
I recently bought a fan to to try to drop the temperature of the aquarium using the evaporation method. I'm working more on this because I think the temperature change is the greatest stress factor on my aquarium.
3~ How large is the tank?
20 gallon
How long has the tank been set up?
9 months
4~What type of filtration are you using?
Eheim Liberty 130 (Filter floss, Seachem Matrix and Purigen) and some other cheap hob filter with a slow flow and Seachem DeNitrate.
5~How many fish are in the tank? What kinds of fish are they and what are their current sizes?
10 Neon tetra
7 Neon Negro
5 Corydora cats
6~When is the last time you did a water change and vacuum the gravel? How often do you do this? How much water do you remove at a time?
I used to change 10% water weekly. After the initial signs of something wrong (fin rot and white patch on the small fin), I started doing 30% weekly or more
I always vaccum the gravel partially. I didn't used to frequently vacuum under the rock and the fake plants, but did a few times after the disease started. It always stress the fish a lot because I have to remove the decorations.
7~How long have you had the fish?
Had since the beginning, after doing a complete fish-less cycling. A corydora cat died for no apparent reasons a few months ago.
8~Have you added anything new to the tank--decor, new dechlorinator, new substrate, etc.?
No
9~What kind of food have you been feeding your fish, have you changed their diet recently?
Loots of different types of food, see picture (no easy access to other kind of foods)
