Underwater Led Lights

I bought these for my 5 cm LED aquarium, they go under water in the bottom of the tank, but they continue to turn round. How can I paste them in a fixed position (not permanently). Would blue tit work?

francesle is correct, the only other optino that I can think of is the one who lies to the oppoxy taink fish and that is permanent!


How about using one of thoes suckers??

If you send me an email with this type of light you have I might beable to find something better for you to use!

The only two options are either good cupping (already suggested) or the weight of bands normally used with plastic plants.

You can try to use suction cups

Epoxy

and if it goes in the tank I think you should try silicone aquarium - its silicon largely steady, but without antifungal orders it. You can DIY by the substance, but you must be sure it is pure silicone, nothing else. It is more stable than what you want, but I think you can take if off when you're finished and want the UN-splice. Not to mention, especially, in my opinion, most certainly not his intent to annoy your fish with nasty chemicals.

I'm peronsally very careful what I put into my tank so I would not risk tack blue - I do not know how it works under water anyway. I think it would eventually break down. However, I am not sure about that.
