Hi there,
I have a 5G tank with a pair of gourami (I am not sure of the species but look like red honey for me) and a chinese algae eater (which loves sucking the scale of the gouramis). The male gourami has been making bubble nest recently and he kept chasing the female gourami away. Today I realised there is some kind of injury on the fin of the female with the pictures attached.
I would like to know if I should keep the female in the current tank or move her to another tank which is an Amazon biotope with 5 skirt tetras? I am not sure if the injury is a bacterial infection or a physical injury. I do not have a quarantine tank unfortunately.
The water parameters are normal
pH: 6.4, GH:7, kH:6, nitrates, nitrites and ammonia: 0, temp: About 72 F or 25/26 C
Thank you in advance.
