That Fish Blog – Aquarium Advice and Information

One of my first ever experiences with fishkeeping was with a goldfish won at a carnival – I thought it looked hungry and dumped an entire container of fishfood into the bowl. At a recent family picnic, I found a pretzel in the top of my small freshwater system courtesy of my four-year-old nephew and after a lesson on not feeding Aunt Eileen’s fish when she isn’t in the room, we all realized that the cycle is truly continuing (especially since that particular nephew loves to check my aquarium maintenance skills and point out all of the spots of algae I missed). I can’t wait until he has long enough arms for me to put an algae scrubber in his hand.

So how do we keep the aquarium hobby fun and safe while turning our little “helpers” into future aquarists? Here are a few tips that I’ve come across while working at That Fish Place, in my prior naturalist experience at a South Carolina state park, and with my own two nephews: Read More »

Your reef tank may be immaculate except for a rusty-brown dusting of diatomic algae on your substrate. Tired of siphoning just to have the diatoms come right back? Relatively inexpensive and highly efficient, a sand-sifting sea cucumber may be the solution you’re seeking.

There are many species of sea cucumber available in the aquarium hobby. They get their name from their elongated, cylindrical body shape. Some are colorful, some are not, some are smooth, while others appear knobby or textured. Some are filter feeders that cling to the glass, waiting for food to come to them in the water flow. There are three specific types of sand sifters that are commonly offered which do a really great job cleaning up your sand. All of them belong to the genus Holothuria and they are very efficient at what they do.  Read More »

After Jose’s blog in May about some of our coworker’s mishaps and misadventures, I’ve been badgered and teased (again) about what we refer to around here as “the eel incident”, one of my own prize foibles that Jose had forgotten when he wrote his blog. Since he wants to tell all of you anyway, here it is in my words….

Along the back wall of our fish room, we have two large coral tanks side-by-side. Now they are coral tanks, but at the time of this incident, we used them for particularly large or aggressive saltwater fish. In the smaller tank on the right, we had a green moray eel affectionally known as Captain who was about three feet long. The other tank had another eel that was about four feet long and was from the old incarnation of our 700 gallon display tank where it used to live with a huge Bumblebee Grouper named Buzz. That eel wasn’t named, so I’ll refer to it as eel B. Read More »

A few hundred years ago, people in Western cultures like 16th century England often drank very little water. Because of untreated sewage draining into water sources and contamination in rivers, other beverages like beer and wine were actually preferred as safer choices. As technology and our understanding of health and technology advanced, we came up with more ways to purify our water sources. At the start of the start of the 19th century, a scientist named William Cumberland Cruikshank found that chlorine would purify water by killing microbes and bacteria like the notorious E. coli. Chlorine is still used in most developed countries to make drinking water safe and chloramine, a combination of chlorine and ammonia is starting to overtake even this old standard. Read More »

Footprint

This is more than just the actual size of the aquarium. Obviously, a 180 gallon tank would make a poor desktop aquarium just as a 10 gallon tank would be an inadequate room divider. Measurements aside, it is important to also consider how much weight the floor can support, particularly if you’re considering a large tank on any floor with open space beneath. In the 19^th century house I live in, I’m fairly certain that a large tank would go straight through the floor and end up in the basement. Some apartment complexes won’t even allow larger aquariums, especially on upper stories. A gallon of water weighs a little over 8 lbs, so water weight in addition to substrate and ornamentation can spell disaster on a weak floor. Saltwater aquariums are also generally going to be heavier than freshwater aquariums – the salt in the water and live rock used in most tanks increases the weight. Read More »
