the massive, 60 foot tall kelp in the Monterey Bay Aquarium is a local, cooler water variety. I used to fish the central coast kelp beds for rock fish, chili peppers, sculpin, bass and ling cod, and troll the open waters for king and silver salmon. all cold water fish. As you might know, the California waters north of LA are in the 55-70 degree range through out the year. but provide a good cool temperature for raising Catilina Gobies. But, like the kelp, the gobies don't survive long in tropical temp reef tanks above 70 degrees. The gobies are very pretty and bright red. you just need a really big chiller. the california kelp can grow 2 feet a day. who has a tank that big? other than Monterey Bay Aquarium?
If you do, we would really like to see it!!
