So Ive had 4 Harlequin Rasboras for a year next month. They have been healthy pretty much that entire time actually haha. yay!
They have always had a white spot on the tip of their lower jaw and I always wondered about it...
Anyways, about 4 days ago I came home and noticed one of the rasboras couldnt shut his mouth all the way. Since then it seems that it gets better, then gets worse again. Sometimes it will be (mostly) shut when I walk in, other times it looks like its pushed forward and open. He is still eating from what I can tell, and is still active. Although he is breathing a little faster than the others.
I do water changes every week, with siphon. All live plants, temp around 80. 29gal.
When I do water tests everything is good. No ammonia nitrite. there was a TAD nitrate the last time. Im going to do a water test today.
any suggestions on whats wrong??
I really dont want to loose one since they have always been together...
