Betta Fish: Any tips to improve my tank

Dumbo the male elephant ear betta

Tech Side:

Tank 14 Gallon Imagitarium

Filter Imagitarium HOB 20

Heater Aqueon Submersible 100w

Plants:

2 wisteria (Hygrophila difformis) (just propagated one off from the other)

2 Java Ferns

Duckweed

African Dwarf Grass (not fully established but doing well)

Java moss (same as dwarf grass)

(Thinking of adding one or two Anubias)

Misc items:

Adding/Replace Indian Almond Bark Bi-Weekly

(Maybe switch to extract as I have it?)

Two rock piles for decor

A root tunnel decor (deep water hide)

Floating artificial log (high water column rest)

Stone circle in “8” shape decor (enrichment and betta somewhat uses to nap in the higher one)

Also have some ramshorn snails in there as well (was mistake but there not to hard to manage)
