ACANS Suddenly stopped opening

[arkal339]

Any idea on why my acan suddenly stopped opening ? All my parameters are ok. Any suggestions would be appreciated.

They have been with me for more than 8 months and were perfectly opening and multiplying as well.

Not really. I did add a new light but reduced the intensity.

probably the new light having a different spectrum/wavelength variation from your older one. just leave the light settings consistent on your new one, if they’re healthy and your parameters are stable it should extend again in a week or two

I dropped temperature to 25.5 from the earlier 26 degrees
Would that have made a difference and acan not opening ?

doubt it’s a matter of temperature. i would avoid making too many changes if i were you. odds are they will take even longer to re-adjust
