My granchildren have given me a bag of glow-in-dark pebbles i washed them in boiling water to clean them have put them in tank .now have just thought what if ? ,do you think they could add to water prob,s & a few of them are floating round the tank as they seem to have air bubbles in them the 2 guppys i have in there seem to like to chase them about or is it that they
are afraid of them the 1,s that have settled on the bottom have piled up with the other pebbles i have in there so fry ar,nt taking any notice SUE

I hope that the glow in the dark paint is not toxic.It may leach something into your water.Keep a close eye on how your fish are acting and watch for change.
I don't think you can test for it with the kits we have.

If you see them start to act different remove the rocks and do a water change!

they dont seem to be painted on solid bits nothing can be seen colouring water but will keep eyes open for any changes thanks sue
