*AHEM* jewfish Goliath grouper!
(Jewfish is apparently an offensive term now, and the documenters here obviously didn't get the memo)
Do we also have to change Black Grouper to African-Atlantic Grouper?
I heard one idea of putting a “skirt” around old oil rigs, the purpose of which would be to catch and deposit an increasing amount of inorganic material, slowly building to a steep peak, with the rig atop it. By that time, the rig would have decayed. But if designed well, the peak would continue to widen, creating an underwater island conducive to life.
Other things could be added, like scuttled ships, so that eventually a reef would start to form as well.
There is no Christianfish, evidently....
