triggerfish 55 gallon

Even the niger will cause issues later. Triggers just don't do well with other fish in home aquariums. Most don't do well in home tanks regardless of what you do. Nigers will grow to a good 12" or more.

Keep the tang and the clownsfish.

I now have the striped trigger in the 55 gallon tank alone.I moved the tang and clown fish to a 10 gallon tank with a under gravel filter and machanical filter.He should get some size in the big tank by himself.They grow up to a foot or more.

I have owned assorted triggers for the las 10+ years and one of the absolute meanest triggers I ever dealt with was a undulatas. It was ok for a while but just kept getting meaner so I kept moving it into aquariums with larger & larger fish. At about 6" it ended up in a tank with a 16" miniatus and a 4' green moray. It killed the miniatus about 2 months later, I sold it to some guy later that week. What a bastard!!!!! YOur yellow tang will not survive in a 10 gallon. Tangs stress out and often die when cramped in a small tank. Just a thought.....
