Hi,
My tank parameter are:
Water Parameters:
pH: 6.8
Nitrates: 25
Hardness:150-200
Nitrite: 0
Ammonia: unknown, most likely 0
KH/Buffer: 40
Water Temperature:72
Currently, I have a planted community 50 gallon seaclear with 12 neon green rasbora, 18 neon blue rasbora, 30+ crystal red shrimp, 20 Amano shrimp.
I purchased 8 neon blue rasbora and 12 green rasbora and they were added about 3 weeks ago.
I’ve noticed today one of my neon blue rasbora has retracted fins, no spots on the body, still energetic, color is good, and eats. I’m wondering if the retracted fins are a sign of some type of disease? I don’t believe water parameters are an issue as my crystal red shrimp have been breeding without issues in this tank. Any help is appreciated.
