lol Thanks Marty, that is correct no underwater castle's, mostly rocks as my decor, I don't even have fake plants ...
And I agree about being careful using the heater in the tubs, that would be ironic wouldn't it.
"Help all my fish are now flopping on the ground due to a mis-placement of heater in the tub !"
Ok, so fresh water it is... Should have remembered that, I think I've seen that discussed several times on this site.
Good to know about the glue fumes, was not sure if that would be a concern or not.
Thanks all for the feedback.
