Right,
I've acquired a 40 gallon tank:
If you were starting from scratch what would you do with it?
What fish? How many fish?
What plants?
How much gravel - what gravel?
What water temperature?
What ornaments if any?
Nice tank. That pic shows a couple of nice pieces of driftwood, right? To utilize those, I'd go with a South American community tank.
Fish:
2 Pterophyllum scalare (angel), 1m:1f
3 Apistogramma agassizii or cacatuoides, 1m:2f
6 Megalamphodus megalopterus (black phantom tetra) or similar peaceful tetra species
1 Ancistrus temminckii (bristlenose plec)
These fish will probably be happiest at around 77-79 F degrees.
Plenty of plants, particularly Broad leaf dwarf sword and Amazon Sword (Echinodorus bleheri), maybe a Vallisneria species or Tropical Hornwort depending on your taste.
Both pieces of driftwood and maybe a river rock cave or two
Small to medium sized red, brown, or black gravel to show off the plants and fish.
That's my take at least. Good luck with your tank!
