I enjoy the look of the forktailed blue-eyed rainbow and the normans killifishLook at :
Tucanoichthys tucano ( Tucano tetra)
Hyphessobrycon amandae ( Ember tetra)
Nannostomus sp. ( Pencilfish) some smaller varieties: N. anduzei, N. digrammus, N. marginatus, N. minimus, N. mortenthaleri, N. nitidus, and N. rubrocaudatus.
Boraras brigittae ( Chili Rasbora)
Poropanchax normani ( Norman's Lampeye Killifish)
Pseudomugil furcatu (Forktail Blue-eyed Rainbowfish)
If none of these are appealing I can list more.
I read about killifish and it said they are a seasonal fish so they have a shorter lifespan, is this true?
If you have any other suggestions I would very much appreciate them. Thank you.
