could a tinfoil barb live in a planted aquarium without destroying it?
where can u find the cheapest plants?
which is a better substrate:sand-gravel-mixed

1) NO!! Tinfoils and siver dollars are underwater-goats. if you have plants it will be an underwater-desert.

2) Not sure, I buy my bulbs on-line.

3) I use ordinary gravel with and iron added additive.
