He does this rather he has eaten his pellets yet or not. He will even let them sneek a pellet if they want one and not chase them off! Like I said, beyond sweet
Also, aren't Black Neons and Golden Neons just Neons that are colored differently? Or are they a different species? Posted via Mobile Device
The so-called Black Neon Tetra
is a different species from the true Neon Tetra
, as it explains in the profiles; click the shaded name for the profile of that species, it will give you info on minimum numbers, tank sizes, compatibility, etc. The so-called Golden Neon is a un-natural (= man-made through selective breeding) variant of the Neon, but the same actual species.
But you may have trouble here, as Geo alluded to. Your Betta may show no interest in the neons now, and this may stay or may suddenly change; I've no idea as to the age of these fish, and the tank environment factors in to this, along with other issues. But another time-bomb ticking away is the temperament of the neons, and this too may well change. All tetra have lots of teeth, and they like using them; they will often turn to fin nipping when a Betta is in the same tank. This is a risk, and there is no guarantee it will or won't occur, down the road. Betta should never be combined with other upper-water fish for this reason. I would think carefully before adding more fish, as this alone could trigger any of the afore-mentioned.
The inherent traits of a species are programmed into the fish by natural selective evolution, and it is simply impossible to change. Why this fish or that fish behave less or sometimes more aggressive/passive is not known. But the "norm" is constant, and one should always assume the fish will be normal. Nine out of ten times any abnormal behaviour is the fault of we, the aquarist, in not providing what the fish requires.
