My four female Betta Splendus are acting like their normal kookie selves, but I have noticed that their fins are starting to become more and more clear. Some of the fins are splitting and one of them lost a piece (could have been a combination of nipping and splitting). There feces is not the normal brown, it is pinkish red and does not curl like it usually does, more log like.
Is this fin rot? They are eating and acting fine but it concerns me. I have Maroxy, anti-bacterial pellets, anti-parasite pellets, and aquarium salt on hand, but nothing else. (The blue on the yellow one is normal, and that white streak on the dark one is the camera lens reflection).
-4 girls in a 10 gallon.
-They are fed betta flakes, and FD bloodworms, some pellets.
-Fed flakes in the morning and a blood worm each in the evening.
-Decorations (lots and they love them)
-10% water changes every other day
-Heater (for some reason they like it better at about 77-79F range. If it gets hotter they become inactive)
-Tank has been active for 6 weeks
-Nitrites are in the stress zone of the water test that I have, but I have not found a method to remove these yet. All of the other water parameters are fine, but as I change water, it becomes harder (even when I let it sit 24hours and add water conditioner)
Any suggestions would be appreciated :)
