Can I get one or two Niger Trigger fish in my 55gal tank? Will they bother my two clowns, snowflake eel, and my African red starfish?  Fishnerd2000

   Do you wonder where this fish got it's name "Redtooth Triggerfish? Well, this fish has red teeth!

   The Blue Triggerfish, Black Triggerfish, or Redtooth Triggerfish has an upturned mouth with a protruding chin and it's color is a blue to purplish-blue with it's head sometimes going yellowish.

   The first one of these that we saw came to the store wedged in a sea shell! The shell was the trigger's home and rather than try to remove it, the owner sold us the fish, shell and all. When we sold the fish to someone else, all we had to do was bag the shell so the triggerfish got to keep his own home through several moves.

   The Blue Triggerfish, Black Triggerfish, or Redtooth Triggerfish can often be a peaceful aquarium fish, especially if they have plenty of room and are well fed. We have read in one reef book that this triggerfish are okay to keep in reefs, we would still be careful about invertebrates though and keep a watchful eye out for any trouble.

this one of my favourite fish to keep. it is pretty good with other fish although mine did chase and nip my zebra moray eel. one bad point about this fish is it makes hell of a mess in your tank, digging holes in the substrate, and toppling rock work.

    I also had taken a water sample in to my locale Pet store and nitrate they said was high but not high enough to do harm and salt level was high so I fix those problems and to no avail. Never had so many problems with this can anyone help ?

    Some aquarists prefer to keep the salt level low, as low as 1.017 ppm. This doesn't usually harm the fish and it has the benefit of making it more difficult for more harmful things to flourish in your tank.

Hey there,
I have a Niger triggerfish and every time I put a goby in it eats it. Is there any gobies I can put in that he won't eat?

  • Jeremy Roche - 2013-02-16
    More then likely he will eat any that you put in.
