Picture of the Week, Rose Bubble Tip Anemone
Pictured in the latest installment of the AquaNerd Picture of the Week is a rose bubble tip anemone, but not just the regular old run of the mill RBTA. This anemone has bright red tentacles and a deep green color on its oral disc. This anemone isn’t a rare color morph by any means, but [...]
Cone Snail Inhaling Fish on Video
Here’s a video to help get you through this long Monday. It’s a brief clip showing a cone snail, noted for its very deadly venom, attacking and devouring a small goatfish. The snail is a slow assassin, inching closer to the sleeping fish, eventually paralyzing it with chemicals that it releases into the water. Once [...]
Another Rare Two Face Clam Surfaces, This Time from Pacific East Aquaculture
The human mind typically favors symmetry when it comes to determining what’s beautiful. Well, this latest two faced clam challenges that completely, as it’s patterns are nowhere near symmetrical. Back in November of last year, we saw what we thought to be a one-of-a-kind two face Tridacna maxima clam from ReefKoi Corals. The mantle from [...]
Tridacna Clams Spawning in Home Reef Tank
Tridacna clams are some of the most interesting and colorful invertebrates we could put in our aquariums. They have a brightly colored and wildly patterend mantle, can retract into their shells when startled, and can even take up nitrate and free-floating particles when they are filter feeding. Another trick they can do is mass spawn [...]
Picture of the Week, Clam on Clam Action
While traipsing through the local fish stores, we came across a beefy Tridacna squamosa clam and noticed it had another little bivalve attached to the side of its shell. The small hitchhiker appears to be a scallop, and it is tucked away in between some of the lateral scutes on the side of the much [...]
Examining Snails Grazing on Aquarium Glass
In this hobby, it’s so easy to get wrapped up in rare fish and corals, high end equipment, and unusual husbandry techniques that the simpler things often go overlooked. Saltwater snails, which are the workhorses of our aquariums, don’t often get their fare share of the spotlight. It’s understandable that hobbyists don’t focus on their [...]
Picture of the Week, Lettuce Nudibranch (Elysia crispata)
Pictured in the newest AquaNerd Picture of the Week is a Lettuce Nudibranch (Elysia crispata). While most nudibranchs are not desirable in the home aquarium, this little sea slug serves one very beneficial function…consuming unsightly algae. The lettuce nudibranch, which technically isn’t a true nudibranch, consumes different types of algae from the rockwork and incorporates [...]
Giant Fireworm Pulled from Reef Tank
For years, aquarium keepers have been telling stories that would seem a better fit in an old pirate’s tale than from a reef tank. These hobbyists have reported elusive and giant worm-like creatures that would attack fish, kill clams, and occasionally wander out into the open to sting aquarium keepers working in the aquarium. These [...]
Peppermint Shrimp, the Swiss Army Knife of the Invertebrate World
The Peppermint Shrimp (Lysmata wundermanni) is a very common saltwater aquarium shrimp. It is relatively inexpensive, is easily accessible by the hobby, and performs many tasks that make it an attractive aquarium inhabitant. In terms of accessibility, the peppermint shrimp can be collected all over the US Gulf Coast and eastern seaboard, and various other [...]
Picture of the Week, White Feather Duster
Pictured in this installment of the AquaNerd Picture of the Week is a closeup of a white and red feather duster seen in the same nano aquarium that last week’s ORA Sprung Stunner was found in. The heavy blue lighting from the Kessil Ocean Blue A150W LED pendant really allows the feather duster to stand [...]
