I am not sure where to put this in the forum, so here goes.
I am setting up a 10g
betta tank for my son. He is a big car freak, and I found a perfect decoration for him at Petsupermarket. It is a car that looks like it has sunken in the water almost like a shipwreck, but a car. It is big enough for a betta to swim through all of the holes, but I was concerned about the sharp edges of the cutouts. I have a large and small file, and I have filed most of the problem areas to a satisfactory smooth level. Now my question is this: Is there any kind of silicone filler that I can use to fill in some of the harder to reach places that the fins might get caught on? I have heard people talk about the silicon to attach things in their aquarium. Would that stuff work for this?
Thanks
