This is my 3,5 gallon tank for betta after 12 days of cycling. I tried to create a biotope environment as it is in a rice fields, so I used low light plants. I'm very happy that I could get cladphora that is on red wood branch and two nice bushes of anubias nana.
On a front right is a copule of crypts, on a left is sagitaria, and behind valsineria and windelow. Riccia is floating on the surface so that betta can create bubble nests on it.
Water has brownish colour which is created with peat granules which also lowers pH in tank.
In a 2 days I will put neritna snail inside for inner cleaning of thank, and red cherry shrimp for extra red colour in tank and, to be honest, to provide live food for betta (they are highly reproductive and betta loves to eat small shrimps).
Lamp is 9W over-top and there is hang-on filter, not so good, but OK for this small tank.
I will put betta inside in a 10 days.
