White bubble on danio’s mouth! #1
Hi, has anyone come across this strange bubble growth like on my danios lip? It originally started off as a small lump, got bigger, disappeared and now it’s grown and almost ready to pop!

What a great photo and lovely fish.

Is the fish behaving and eating normally? How are the water readings for ammonia, nitrite and nitrates?

This thread ... 29910&keywords=lip+bubble is interesting and possibly similar - read it through completely from start to finish, particularly the aspect about whether you've made any water changes recently with particularly cold water.

Possibly microsporidia which is a protozoan infection. Use Paraguard to treat.
