That Fish Blog – Aquarium Advice and Information

Almost every saltwater aquarium that has had live rock or corals has bristleworms. They may not be obvious, you may not see them, but chances are that they are there…and their “attacks” are some of the most common injuries that hobbyists encounter. Read More »

With all of the technological advances in the aquarium hobby, I thought it would be nice to take a look at one of the most rudimentary and long-standing pieces of equipment in the industry – the Undergravel Filter.

Undergravel filters get a pretty bad rap. They are sometimes considered to be a relic of aquarium history, but are they still serviceable? Some hobbyists swear by them and some hobbyists swear at them. How your tank runs using an undergravel filter is dependent on a couple of factors – set up and maintenance. Let’s take a look at some of the common problems associated with undergravel filters and explore some solutions. Read More »

I don’t think that there is any great debate over what makes an ideal “starter fish”. For decades, bettas have been recommended and successfully kept by budding aquarists of all ages. These little fish can lure just about anyone with their brilliant colors and impressive fin displays. They make great starter fish because they are low maintenance and not very demanding. A few bits of food and a weekly partial water change is about all they need. For just a few dollars and with a little creativity, anyone can have a beautiful betta habitat in their home or office.

There are a few things every aquarist should have on hand, especially for saltwater and reef aquariums. Algae scrubbers, food for their fish, extra filter media…and first aid supplies. Even the most cautious of us gets scraped, stung, poked, cut, irritated and altogether abused sometimes when we work on our tanks. The supplies you may want to have depends on what you have in your aquarium (freshwater aquarists may not need many of these items) and your own medical history (if you know you are allergic to something like bee stings or salt creep or fake SCUBA diver ornaments, you may need some extra items like an Epi-pen or special medications).  Keep these items in a clean, waterproof container in your aquarium stand or nearby for easy access.

Over the last couple years, I’ve heard much debate over the use of LED lighting for reef aquariums.  Has the technology really advanced to the point where LED is a viable option for lighting a reef aquarium, or is it just a fad that has no real substance?  Most of the opinions on the subject are heavily influenced dependent on which side you are looking at the technology from.  I have been told many times that LED cannot sustain photosynthetic corals. Some believe the light production is not of adequate quality to keep a reef tank long term.  Not surprisingly, this has mainly come from manufacturers of traditional lighting sources (T5, PC, Metal Halide), and some have been highly critical of the LED technology.  On the other hand, the manufacturers that have invested in LED technology are adamant about the quality and validity of LED lighting.  Those on each side of the fence are understandably trying to defend their own interests in the debate between traditional vs. LED lights for use on reef aquaria.
