Once to Twice (I think)
Our other thing, is Dad siliconed some netting and these bouy type things to the back to give it a "under water" impression, could that be it?
It has a heater, a fluval filter, some driftwood, gravel, plants, a boat ornament, a cave that lights up.
2x angels
15 or some-thing neons
2x male guppys
4-5 corys
and thats about it!
