I guess 3 would be out of the question. Think it would fit?
I would assume the tank is well-oxygenated since it's extremely well-lit with lots of plants, and Bettas take most of their oxygen from the atmosphere...
I would not mix betta with these loaches, they are poles apart in their needs. Betta need quiet water, a stagnant swamp suits them to a "T". This loach needs a flowing stream, quite the opposite. Water movement is not only a question of oxygen, but of providing the natural environment the fish species will feel "at home" in.
Suitable loaches for a betta are the dwarf species, we have two in our profiles. The more common dwarf or chain loach, Yasuhikotakia sidthimunki, or the banded loach, Yunnanilus cruciatus. I have both of these, a group of five each, in my 33g SE Asian pond tank with smaller gourami species, Dario dario, lambchop rasbora. They are splendid together. A small sponge filter circulates the water but minimally. And lots of plants esp floating. My red tiger lotus are now almost covering the surface with leaves, and the gourami (Trichopsis pumila and Parasphaerichthys ocellatus) spend most of their time cruising beneath the floating leaves, as do the Dario dario from time to time. The two loach species browse over plant leaves and stems, wood and the substrate.
