The Bristleworm- Friend or Foe?

Ask ten people in the hobby about bristleworms and odds are good that at least half of them will tell you that they are terrible, horrible creatures that will kill your fish and eat your corals. There are a lot of opinions on these lowly creatures, and I have always argued that anyone that tells you that they are villains has resorted to judging a book by its covers (or a worm by its slime and spines) and overlooked how useful these guys really are. 

First of all, for those of you who don't know, a bristleworm is a common critter to find in any reef tank squirming its way through the sand and rocks in a never ending quest for food. There is no denying that they are not the most handsome of creatures, something which prevents many people from seeing their true beauty. Look upon the loathsome bristleworm and shudder!

Even this fuzzy nighttime picture doesn't do this guy any favors, there is no denying it. So why am I such a fan of bristleworms?

First of all a small disclaimer, I like all kinds of creepy crawlies and gross critters so I am predisposed to be partial to them and give them a pass that some people might not. BUT even if I wasn't a weirdo like that I would still argue for them, and here is why:

  1. Despite what many people think, they don't eat your livestock. If you see a bristleworm eating something in your tank it was already dead or close enough to have made no difference.
  2. They are free clean up crew. In the world of saltwater tanks the clean up crew is a vital piece of biological tech we have at our disposal, but all the hermit crabs and snails in the world won't get everything and they certainly won't eat all the stuff the various worms in our tank do. Bristleworms are free, repopulate themselves, stay hidden most of the time, and eat things that we don't want lying around our tanks.
  3. Liverock and substrate needs to be maintained. These guys get into places that almost nothing else can and they keep those areas free of detritus that would otherwise buildup and create nitrates and phosphates. No one wants those things getting out of hand!
  4. They help maintain the ecology of your saltwater tank. Of all the worms you want in your tank, these guys are the top dogs. They keep the other ones in check and prevent population booms of other critters.

Of course just like anything bristleworms have their cons as well. They can get out of hand if your tank isn't maintained properly and too much food is introduced to the tank, leading to these guys getting out and about more which most people don't enjoy. Also, touching them is painful so that is best avoided. Their close cousin the fireworm is downright dangerous, but thankfully it isn't often seen in home aquaria nowadays. 

So the next time you see the lowly bristleworm sliming its way through your tank late at night or in the evening look the other way and let it do what it does best. Or take a moment to marvel at an evolutionary powerhouse that has been keeping the world's oceans clean for millions of years and will do the same for your tank for as long as you have it. 

Inspired by nature...

I know what you're thinking. "What are these fish nerds talking about?! What does inspired by nature mean?"

That's what I'm here to tell you.

Paul and I have spent a long time keeping aquariums and building systems for fish, invertebrates, and plants to thrive in. We've spent time on the front lines of the retail world in little mom and pop fish shops and in the thick of it at one of the major big box pet retailers. We've worked as service technicians for other people doing it their way only to go home and do it our way. That isn't to say we didn't learn anything from the people we worked with and worked for, but at the end of the day we came to trust our way the most. The way we have come to believe is the best way, the way that takes its cues from nature.

What does that mean? We don't like to rely overmuch on chemicals. The most common aesthetic issue that a customer is concerned with is unsightly algae and many people reach for an algaecide first and ask questions later. That is our last resort. Imbalances between lighting, fish waste, overfeeding, and overpopulation are the most common reason for algae and so we work to achieve a balance between them.  Doing so solves the problem at its root and leads to a healthier more stable aquarium over the long term.

Plants are wonders of nature, little machines that turn waste into oxygen and beauty for our aquariums. Fresh or salt, every tank can benefit from a little greenery (or red in some cases) and we are always looking for new plants to incorporate into the systems we care for. Not only do they help balance an aquarium, they encourage natural behavior from the fish and invertebrates that call your aquarium home. Not to mention they are beautiful!

Everyone loves to ask me what a specific fish "does." Many of us grew up with the notion of fish that perform jobs within a tank, and while this frequently wrong or at least misleading there are a great many critters that do serve the role of aquarium caretaker. Saltwater reef tanks especially are home to innumerable small creatures that tirelessly work day and night consuming algae, uneaten food, waste, and the occasional body hidden away in the dark corners of your aquarium. These little guys are the unsung heroes of the aquarium world, and though many of them are unsightly there is a beauty in what they do. 

All of this is just a little bit of what it means to be inspired by nature, just some of the things we focus on when we set up and maintain a tank and this isn't the last time you'll hear me talk about what it entails.    

Public Aquarium Review: Florida Aquarium

Address: 701 Channelside Dr. Tampa Florida 

Date: 12/26/17

Amount of time to see aquarium: 2 hours

The Florida Aquarium is a medium sized aquarium located in the Channel District of Tampa Florida. This aquarium is focused on showing native wildlife of Florida but does have a large collection of animals from other parts of the world. My favorite part is the large bio dome area which starts with displays on freshwater springs and ends with exhibits on bays and estuaries. In the bio dome area are free flight birds and open exhibits. Upstairs is a section on Madagascar with in the bio dome. There is also a large tank with sharks and other fish of Florida's reefs. Outside they also have a water play area for kids. Overall the aquarium shows off Florida's wildlife and other parts of the worlds oceans very well.

Public Aquarium Review: Key West Aquarium

 

Over the years I have been to many different public aquariums along the eastern seaboard from large ones like Georgia Aquarium to small ones like Jenkinson's Aquarium. The first one I will be giving a review on is Key West Aquarium. 

Address: 1 Whitehead St. Key West Florida 

Date: 12/21/17

Amount of time to see aquarium:  1 hour

Key West Aquarium is a small aquarium with a focus on the local marine life of the Florida Keys. The aquarium first opened in 1935 but after a hurricane it was used as a rifle range until 1946. Overall it was a small aquarium but it was interesting to see the history of the aquarium with its older displays.

Current Fish Breeding Projects

First, I would like to introduce myself. My name is Paul and I am co-owner of River to Reef. I am part of a few local aquarium societies and an active member in most of them. One thing that many aquarium societies offer is a Breeders Award Program (BAP) to encourage members to breed fish and help with conservation by breeding rare and hard to find fish and to provide a local source of fish. The rules are that the member must bring in 6 babies from the fish they have bred at 60 days old. Points are given to each species bred which range from 5,10,15,20,and 25 points. Currently I am trying to breed the folllowing

Tiger Limia (Limia sp. Tiger)

Goldbelly Topminnow (Girardinus falcatus)

Pelvicachromis silviae

Poecilia sp. Pelenque

Orange Laser Cory (Corydoras sp. Cw010)

Pearl Cichlid (Geophagus brasiliensis)

Convict Cichlid (Amatitlania nigrofasciata)
