 Too many people pick up fish by lower jaw.....
You might think you are releasing the fish, but you are really killing them....
Many people pick up or hold fish by the lower jaw, either by hand or by using a fish grip tool or pliers. A recent study was done doing this, where the fish were tagged, and all the larger
fish turned up dead a few weeks later. They determined later that the fish ended up with dislocated jaws and couldn't eat, or it damaged their gills which is attached to the lower jaw. This
means you must ALWAYS support the fishes weight if you plan on releasing it! You may see them swim away when you release them, but they are floating up dead either from starvation or gill damage
after they have been released. This is important to know as fishermen often try to do the right thing by releasing it, but may not realize they are killing and damaging the population even though
they are being released, and this is even more important with larger fish that support more weight. Always hold the belly even if holding by the mouth so you support their weight,
or use a non abrasive net, especially you would like to catch them again in the future or help the population reproduce.
Things to help fish survive when you catch and release:
1) Support their weight by holding the belly or using a net. Don't hold by lip or gills, its damaging and killing them within weeks of release.
2) If you plan on releasing, use barbless hooks. It makes it real easy and quick to unhook fish, and doesn't tear or rip.
3) If the hook is swallowed or in the gills or gut, just cut the hook or line above it, fish have been caught with old rusty hooks in them, so they can survie this. It will rust and fall out.
Tearing or wiggling or pulling the hook will most likely lead to the death of the fish.
4) Take pictures quick, and support the fish weight for the photo. Keeping them out of water longer can kill them, even if they swim away, so the quicker you do this the more you help.
5) Release the fish gently in the water, don't stun it. Try not to handle it to much as the more slime you remove from it the more damage it does. This protects their surface.
6) Following simple rules like supporting their weight, not tearing hooks out (going barbless makes things easy fishing too), and getting them back in the water quickly can save fish for generations to come!

I also think it helps revive the fish if you hold the tail and slide them forward and backward in the water until they swim off. I've had a few float when I released them, but then grabbed the tail and revived them this way, and they swamp off.

I don't know about the other stuff..but ..Like most fishes, the reef tigegrrfish undergoes heterosexual reproduction, in which there are separate male and female parents. Reef fishes are egg-layers, and the eggs are externally fertilized by the male parent. Nests are built by the female parent, in which the eggs are fertilized and cared for until they hatch. The newly-hatched young are also looked after by the female parent
