I saw this stuff called Deco Art Gel Base on Big Al's Online, and I was wondering if anyone here has used it in their tanks. (with goldfish, tropical fish, bettas, etc) I've used gel-like stuff before for this arts and crafts project, and the problem was that the gel floated! So, I don't even know if this stuff works.

So, I was wondering if anyone has had any success with this type of substrate before. Any comments would be appreciated!

The main part I would have a problem with is that most of this stuff that I have used in the past with crafts is that its so small that the goldfish could eat it, and it being soft they just might digest it, I dont think it was intended for the larger fish

IMO
