lol he wanted a betta but i thought that he would do water changes ect but hes all intrested now lego is menstioned hes making a cleaning schedule
Legos should be safe ,kids chew on them all the time and dont die. Although agree but it does not mean it's non toxic especially when sanded/bleached.
Lets see, we have had matchbox cars,keys,bottles,coins,BBs,even silverware..Not sayng to do them all but the betta lived..lol
Very dangerous statement as coins will cause massive wipeouts and/or unbearable sight/symptoms to look at. I havent tried the rest though nor will I ever.[/QUOTE]
I think weighing down the lego plate with rocks would probably work pretty well.maybe assembling the lego structure upside down and filling the spaces with wet sand would work to keep it from floating? either that or silicone a flat lego plate to the bottom of the tank and build on that.
