Tail rot?

[Cohazard]

Soo, I recently got 4 irrubesco males.

So far they're eating well and are getting along.

However, one of them showed up with a white top to the top part of it's tail. I didn't think anything of it at first, it didn't look out of the ordinary, but today, that white tip of the upper half of the tail has extended to the base of it's tail. The tail is still in tact, just that the top half has changed color.

I haven't been able to see him open is tail all the way (they rarely do that). What could it be?

I'll try to get a pic up tomorrow

Irrubescos are notoroious for biting each other's fins (and bodies). Its probably some fin rot.

Clean water and melafix should clear it right up, but if it turns into an infection you might need to use some sort of antibiotic. Try the clean water and melafix though first, lots of water changes, follow the melafix directions.

Okay will do, thank you Myaj!

They probably do get a little nippy with each other when I'm not around, when I do have time to observe them, they are usually in different parts of the tank hiding.

I have a moonlight, and so far I haven't seen them very active at night.

Make sure that tank is HEAVILY decorated, breaking up their lines of sight.

the tank is heavily planted, and growing
