I recently did the DSM and everything went really well. After 6 weeks I flooded the tank, tested the water every day, did about a 5gal water change (it's a 32 gal tank). Anyway, params leveled out:
NH4 0.25 (my tap water measures 0.5)
It's high tech tank.
Anyway, I added 9 amanos and that went well and they are are eating well and all alive as best I can tell (mind you, I never see all 9 at once, but there are lot of hiding spots in my tank).
A week after adding the amanos I added 4 Oto's (this was on Wednesday, it's Saturday). The Oto's are the only fish in the tank.
Today, I noticed this:
Please note I have a lot of micro bubbles in the water from the inline CO2 diffuser (as seen the first photo, those white dots in the water are bubbles). You can all see how much pearling is going on with the HC.
Anyway, is this something on the fish or is normal?
All 4 seems to have it but they are all very active and eating very well.
Any thoughts? If it is something, I want to catch it quickly. I'm not sure if it's new or always been there, it is hard to see with the naked eye they are so small and I only really noticed when I was taking photos today.
Thanks in advance!
All the best,
