makes fragging easy
I used these rocks to build a tower for my devil's hand coral. Easily arranged and epoxied together. Nice coloring. Would work great for fragging.

Beautiful rocks for anemone tank.
It leave a pink residue on hands when cleaning the rocks , I think it shouldn’t that’s why 4 starts , they are beautiful rocks. Below a picture of 2 bags 2.5lb on a 38 gal fish tank (30x22.5 inch), waiting for a second delivery of bigger rocks.

FYI, Not for plugs.
I expected holes for plugs. There are none. These are not made for that, so know that in advance.

Frag Rock arrived, colouring comes of very easily so will have to see what that is like (perhaps normal for this type of product) when used, I've not added to tank yet, I'll be checking my water closely once added and will update the results.
