Is this ich on my neon tetra?
Today I noticed one of my neon tetras was behaving a bit odd, and when I looked at him up close he had white spots all over his body. Is this ich? I live in the EU, what products can I use to treat it that are available to me? Should I treat the whole tank?
This fish lives with 9 other neon tetras, 10 Pseudomugil luminatus, 10 Inpaichthys kerri "Superblue", 8 kuhli loaches, 3 blue neon gobies, 3 pearl gouramis, +20 neocaridina shrimp, 7 pinocchio shrimp and 1 blue jelly snail. They live in a 200l heavily planted tank at 24ºC, 7.3pH, 0 ammonia, 0 nitrites and 15 nitrates. The tank has been set up since November and I started adding fish 1.5 months later. There is a small cyanobacteria problem that we're treating with Easy-Life BLU1000 Blue Exit, but we just returned from a 3 week long holiday and the tank was in my parent's care, and it was covered in cyano. We cleaned it all immediately and started treatment but I assume it must have been stressful for the animals.
Thank you for your help.
