Picasso Triggers are great fish to keep. i have a picasso and a bluethroat trigger in my saltwater reef (yes, i have soft corals, anemones, and polyps with them)... (more)  some kid

   The Picasso Triggerfish or Huma Huma Trigger (Whitebanded Triggerfish or Painted Triggerfish) is a very popular triggerfish probably because of its' very interesting color and unusual patterning.

   It is quite striking with the line markings of yellow, blue and black adorning a mostly white body. This fish will emit a 'whirring' sound when it is startled.

   To maintain a peaceful tank that houses triggerfish, be sure to provide lots of room and a cave or rocks for a retreat area. Also house appropriate fish together that have similar needs and can hold their own. In this case larger protein eaters such as groupers, surgeonfishes, and basses, Some eels and puffers can be appropriate too.

  The Picasso Triggerfish or Huma Huma Trigger are known to have a pretty good disposition for a trigger and are generally a peaceful fish.

Picasso Triggers are great fish to keep. i have a picasso and a bluethroat trigger in my saltwater reef (yes, i have soft corals, anemones, and polyps with them) and they are doing great! they never bother any of the other fish or corals, and always come to greet you at the front of the tank. they are very herdy, and should mention that i am a kid, and this is the first saltwater tank i set up. they are great, and i would recommend them to anyone who wants a smart, hardy, and peaceful saltwater fish.

    Who says you can't keep triggers together. I have two Picassos, an Undulate, a Clown, a Nigger and an Indian Trigger in my tank. They all live happily together without any issues. At one stage one of my tangs had an issue with my clown trigger but I took the tang out for a week and this resolved the issue.

Been in the saltwater for 9 years, recently decided to go on the aggressive side, thanks to wife who fell in love with a 6inch humu humu beautiful! As many may hear this is not one of the aggressive triggers, story short, been going to local pet shop 26 years nothing this women daughter of owner wouldn't handle. When I asked for this fish, she refused and asked her brother to get it for me. Needless to say there was human blood in the tripled bag I brought home, been watching this fish for months, I put him in with a same size nigar trigger and he kicks his butt on a daily basis, by the way tank is 125 gallons but he lives peacefully with a few damsels and a snowflake eel and a clownfish. VERY AGGRESSIVE!

What are some picasso trigger fish tank mates for a 75 gallon fish only tank?

  • Jeremy Roche - 2012-11-02
    Some great choices out there; snowflake eels, smaller groupers, lionfish,  larger clown and other as long as not too small.  Triggers can turn at any time.

We have just purchased two junvenille triggers (one clown & one picasso) we were just wondering if it is possible to keep these two in the same tank, they have been travelling fine so far (they stay out of each others way). We also have in the tank a Blue Ribbon Eel, a Lion Fish, a Bird Nose Wrasse.

  • russell emerson - 2012-02-11
    The blue ribbon will be dead meat right away, and the lion fish will get the same treatment in the near future. The bird wrasse will do all right, but I would suggest a grouper or a sailfin tang. Trigerfish are my favorite. I have kept almost all of the species and I can promise you this. As bad as the clown trigger is going to be when it grows up, the Huma can and will be just as bad. Think about it like this, it's like putting a lion and a tiger in the same cage, and then think about what you would put in with them.
