Hello.
I am currently cycling a 240 litre tank with neon tetras (which I explained in my other thread) and I was looking at my neon tetras and some of them have red gills.
Is it normal for them to have a little bit of red on their gills or is it ammonia poisoning?
I am quite worried so please answer.
Thank you.

Gills are red because they are full of blood which absorbs the oxygen from the water and transports it around the body to where it is needed. However, the gills are mostly masked by the gill covers which are silver. These open and close as the fish breathes in order to pump water over the gills. When they open the gills can be glimpsed.
