i was uncovering rocks in a dirty part of Redondo Beach, CA tidepools when i was surprised to find a CA 2-spot octopus. Body was about the size of a lemon, tentacles maybe 5-6 inches long (though i suck at estimating). the color blew me away. i have a common brown octo which changes colors but always brown/yellowish/dark brown. This 2-spot octo today was speckled with blue and green and had a nice pink shade on the underside. a few things to note: i read on here how water parameters have to be impeccable to keep octos, but i'm assuming for tropical ones? because this one today was in REALLY dirty water! 10 feet away was some sort of white film over it, and there was everything from bras to coke cans in this water. my main question is, if one was to take one of these home to save the $30 at a LFS (and for a nicer color), how strong of a chiller would you need? CA waters are usually low 60s, however octos are in shallow water which is a bit warmer, no? unfortunately my 1/15 HP nano chiller only goes down to 73, otherwise i could have a free supply of GORGEOUS octos. i can't get over how colorful it was - much more than the brown ones LFS's sell!
