Pond Boss Forums INTRO Questions & Observations 20' spawn depths

This does not apply to RES but in the Caribbean I have on several occasions watched gray Chromis mass spawn along hundreds of feet of reef length. Their spawn is nothing like RES and would more resemble FHM but they spawn in mass numbers. Tens of thousands of fish over maybe a day or two. But the point that applies to this discussion is that the spawning fish will blanket the reef that descends at about a 45 degree angle from 20 feet depth to 80 or 90 feet depth. A literal blanket of 4" fish spawning for several hundred linear feet of reef. So it appears the depth differential may not affect the eggs much, at least in the case of Chromis.
