The media could not be loaded.  Love the fact that you can place one on top. The down side is that you have too, use a nail filer to smooth the rim of them. Mr bubbles loves going though them

I liked the size, weight and texture of these. Got a pack to put one each in my two betta tanks. I checked for pointy edges- there was only one or two but I can tell the item is cheaply made so it might be different for every order. Mine were fine, I just filled around a spot on the opening to make sure my betta’s fins don’t get caught. I boiled them in water for 10 minutes just to get ride of dust/germs and then put them in the tanks. They don’t float to the top and my girls love them!

I bought these for my 10-gallon saltwater quarantine tank so the fish would have hiding spaces that are a little more natural-looking than PVC pipe, which is what most people use, until I can move them into my reef tank. My royal gramma and six-line wrasse both love these. The wrasse has made the larger one his primary home and spends his nights in there, but the gramma recently started spending time in there as well. They both enjoy swimming through them throughout the day. I also have PVC pipe and the wrasse will swim through that, but for the most part both fish ignore the PVC and stick to these "caves".

These look great and I’m sure the frogs will love them when we put them in their new tank!

The sharpness around the openings worries me. It’s just not very smooth. I like the design though! My fish doesn’t seem to care
