    I went into the store not knowing what to expect. I was actually out looking for a tree to put in my backyard, but all of a sudden, there I was at the fish store. They didn’t know a thing about trees, but boy howdy, did they know everything about coral, tanks, pumps and what not. I worked mainly with Jack, who knows a lot for a young whipper snapper. I actually bought enough gear to even impress my distant grandson, but his mother ended up looking at nursing homes once she had seen what I had done.

    Long story short, I’l be back and soon as the home has a shuttle that stops at this store!

    Ki has been in the reefing business for many years and is very knowledgeable. He is always willing to share his knowledge with anybody. He is reasonable on his prices for his quality livestock and dry goods. Though I can purchase dry goods for a little less on line. I make all my purchases from Ki to help support his business. He is more than just supply stuff, he supplies support for local reefers. He is great!!!

    This place has been one of my favorites for a few years now every time I come in there’s always something new. Having good quality water comes to having good fishes and coral!!!! See it for yourself

    I must agree with Dave. Ki sells corals that will survive. I have bought from other places -everywhere (been in the hobby 5 years) . After many deaths and paying way too much , i always go to ki’s first. he sells zoa frags 3 for $20 thats like $6.66 per frag –CRAZY. And he sells chalices and sps for 3 For $40 thats like $13.33 each I dont know how he makes money but he sure wins my votes as far as best prices, selection and knowledge if i am having problems he knows what to do. I just got a frag of purple death w/20+ polyps for $6.66 . Im happy and im going there today to get more cool corals.
    Great job Ki and Paul and some new cutie working down there!

    Keys Island has the most knowledgeable staff and consistently best quality livestock and Coral that I’ve found in the Colorado Springs Denver area. One of the most amazing things, though are the coral and frags that Ki stocks in his tanks. You can find excellent prices on hundreds of healthy coral frags. I have personally purchased over a hundred corals and frags from this store and have lost less than 1% due to sick or damaged Corals. 99% are still growing and healthy in my reef tanks.
