Gildorph, sounds like you've got some great triggers there. I've heard about the larger triggers (and fish in general) having a harder time getting used to aquaria life.
The blue throat I bought is about 3 inches or so. Still hides in the rocks when I get near the tank. Seems very comfortable in the tank when I'm in the room (and sitting down for a bit).. but move toward the tank and he hides. Poor guy.
yes, only the male has the blue throat.Can you even sex them at a young age?
