So I’ve been working non stop lately due to short staffing and upfront will admit i have not had time to do anything with my tanks. I noticed the other day my orange eye blonde tigers had turned dark blue. So I checked the water and the ph had shot up from 6.6 to 7.6. I added some ph down for a quick fix and yesterday they looked like they were back to normal. Then today I’m seeing blue ones again…. Am I seeing different shrimp in my tank or are they able to fluctuate that quickly?
