Looking for something that's reef safe? The red-eye solorensis fairy wrasse might be a perfect addition. We recommend having a tight fitting screened lid for these, as these active wrasses can be jumpers.

What's in store this weekend? Have a peek!

Twin spot, or clown coris wrasse waking up this morning. This little gal will grow to be a large wrasse and is not considered to be reef safe. She will make her meals from most small crabs and other invertebrates.

Got Bubble Algae? We know a guy...

The pitho crab hails from shallow waters, tidal flats, and seagrass beds in the Caribbean and parts of the Atlantic. These little crabs are nuisance algae connoisseurs, known especially for feasting on bubble and hair algae. They are considered reef safe, but can nip at corals if starved.

We got a few in this weekend, so if you've got green issues, come grab a couple while we have them!

Did you know that anemones can reproduce by binary fission? While that may sound like something out of a story about nuclear energy, it actually means that they can split right down the middle, going from one critter to two. They can also leave little babies, like footprints.

When this happens a lot, sometimes you just gotta have a sale!

We're open Friday 12-7, Saturday 10-6, and Sunday 12-5.

You might not have thought about house plants in conjunction with aquariums, but they have added a great deal of appeal to our front room.

So we're offering plants and terrariums now, at very competitive prices! Stop by and see how well they can spruce up your fish room!

Gorgeous geophagus in a service customer's tank. The pair keeps that fine sand looking good!

This is just some of the driftwood we received in this week. These pieces are pressure washed and sun-dried so they are attractive and safe in your tank. The selection tends to narrow pretty quickly when Zack brings in a truckload, so don't wait for the best options!
