We recently bought three moonlight gourami, 3 neon blue gourami and a thick lipped gourami.
We didnt notice until we got home that the biggest moonlight gouramihad this sort of pink spot thing on its bottom lip.
I have only had freshwater fish once... and for very few months... could anyone help me diagnose this?
And help me find a treatment?
I will try and add pictures later...
Thanks in advance!
