Ooh, looky here! A biotope for dwarf puffers!
Native Plants/Biotope
The following is a list of aquarium plants that are native to the India/Sri Lanka region, which is the homeland of Dwarf Puffers. The purpose of this list is to help someone design a
dwarf puffer habitat using vegetation that would be found in their native areas. This list is not by any means complete, but it may provide helpful guidelines for planting your Dwarf Puffer tank. Please note that the light requirements listed are only the optimum lighting levels for the plants.... most of them will do just fine at lower intensities, they just may not reach their full potential. The light requirement is shown as "Watts Per Gallon" or "wpg". Click on the Scientific Name of each plant to see a photo:

Southeast Asia Back-Water
By: Robert Paul H.
Southeast Asia is home to many of the fish which are in most demand by hobbyists today. The backwaters of southeast Asia are both slow moving and thick with vegetation. Both above and below the waterline live many ferns and bamboo. The streams are packed with organic matter and stained brown by the iron rich red rocks that cover the bottom. You can recreate this environment with the following guidelines:
PH: 6.0 to 6.5
Hardness: 100mg/liter CaCO3
Temp: 75 to 79 degrees
Plants:
Bamboo Plant, Blyxa japonica
Giant Hygrophia, Nomaphila stricta
Recommended lighting:
3 watts per gallon of water
Substrate:
laterite
sand
red gravel
multi colored stones
pebbles
Suitable Fish:
Tiger Barb, Barbus tetrazona
Siamese Fighting Fish,
betta splendens
Clown Loach, Botia macracantha
Zebra Danio, Brachydanio rerio
Honey Gourami, Colisa chuna
Dwarf Gourami, Colisa lalia
Pearl Gourami, Trichogaster leeri
Paradise Fish, Macropodus opercularis
Red Tailed Black Shark, Labeo bicolor
(Dwarf Puffers!!)
The bottom layer of the substrate should contain iron rich laterite for the plant growth, topped with a mixture of sand and red gravel accented with larger stones and pebbles. Seachem's Flourite is a red clay gravel very suitable for this. To make things more interesting you can alternate to have some exposed areas of sand as well as gravel or rock, however the overall look of the substrate surface should be dark with a lot of red color. Broken pieces of red clay flower pots also make a nice accent. The over all look you are striving for is tall, bushy plants in the background and sides, and a rocky foreground. This simulates the plants growing close to shore while the outer areas are littered with rocks.
