Today I received 4 0.25 inch nudis from salty underground. Needless to say after placing them on the rock work and turning my back I’ve lost sight of them. For those of you that have had aptasia and introduced berghias how long did it take till you saw a decline in the aptasia population. I have probably about 12 that I can see and it’s a 25 gallon tank, I know there’s bound to be more hidden in the rock work.
