Hi everyone,
This is my first post so apologies in advance if I do anything wrong. For the record I found similar threads online but nothing that matches the issues I'm seeing.
This is my first tank. I set it up for 5 weeks empty, saw the ammonia spike and drop. Added 14 neon tetras and 6 cherry shrimp at the same time, from the same store. I saw on the first day one tetra had what I assume to be an injury. I did lose 2 shrimp after the first week but the rest have been okay.
Today I noticed red spots on one side of two other fish. Could have been that way the whole time, hard to say.
1~What type of fish is afflicted? In addition, please describe what is wrong with the fish to the best of your ability.
Neon Tetras have Red Gills. I noticed it on one almost immediately after getting them. I assumed it was a birth defect or injury. A month later at least 3 have it, but I can't be sure they didn't before, I just noticed it on two more. All red marks are definitely only on one side the two I noticed it on today are significantly less bad the original.
2~What are your tank parameters (ammonia, nitrites, nitrates, temp, pH)?
Ammonia - 0
Nitrites - 0
Nitrates - 2
ppm
Temp - 77
pH - 7.4
gH - 6
kH - 5
TDS - 400
3~ How large is the tank? How long has the tank been set up?
20 gallon long. 10 weeks.
4~What type of filtration are you using?
I have 2 sponge filters and a Aqueon QuietFlow 20
5~How many fish are in the tank? What kinds of fish are they and what are their current sizes?
15 XL neon tetras
5 cherry shrimp
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 do 2 water changes a week, taking out between 2-4 gallons each time.
7~How long have you had the fish? If the fish is new, how did you acclimate it/them?
Had these fish for about 5 weeks. I sat the bag in the water for 40 minutes and then added them into the tank with the light off for the first 24 hours.
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?
I try to feed them veggie pellets but they won't eat them. I switch between flakes, which they can take or leave, and Hikari MicroPellets, which they absolutely devour.
