David Lass
I am a firm believer that any aquarium will do better with some healthy live plants growing in the tank. This is not to say that average hobbyists should have CO2 injection, high-intensity lighting or always be adding drops of stuff to the tank. With the good fluorescent lights/hoods that are being sold today, any hobbyist can keep many different kinds of aquatic plants ... More»

Hang On Back (HOB) Filters

There is a new generation of Hang On Back (HOB) filters for aquariums that are being offered by the major manufacturers, and they are definitely an improvement in the technology. With the earlier versions of HOB filters there was always a problem when hobbyists went to clean or change out ... More»

Fish Breeding in a Store
David Lass
When it comes to ways to increase sales in your fish department, one of the best strategies is to have some fish breeding in a prominently displayed tank. One of my good friends and fish customers is Lebanon Pet in Lebanon, N.H. This amazing store has, I believe, one of the largest fish rooms around, comprised of more than 300 ... More»

Algae Eaters
David Lass
Algae are very often a problem with hobbyists, especially with folks who are just starting out in the hobby. No matter how many times any of us tells them that algae (either growing on things in the tank, or the dreaded "green water” syndrome) comes from too much food and too much light, hobbyists always swear up and down  ...

Two New Rams
By David Lass
Rams (Mikrogeophagus ramirezi) are a fish that has been around in the hobby/industry for many years. Most rams available for sale are farm-raised, either in the Far East or Florida. True wild rams are not around that much, and when they are they can be very difficult to keep. For years, most of the rams came in from the Far East, in both normal (blue) color ... More»

Angelfish Feeding Habits
By Patrick Donston
Do you recommend marine angelfish, in particular dwarf angels as reef compatible inhabitants? Marine angel fish (Pomacanthidae) are found on coral slopes throughout the tropics. They are much sought after by aquarists and, by many, are considered prizes of the marine aquarium. These fish require careful maintenance because of their delicate nature ...

Painted and Dyed Fish
By David Lass
While I have no problem with genetically modified fish, or fish that are the result of hybridization between two or more species, I am completely opposed to dyed, painted or tattooed fish. I am enough of a realist that I know full well that these monstrosities – there – I said it – are too firmly entrenched in the hobby/industry to ever hope that they would be done ...

Ecosystem Displays
By Patrick Donston
An Amazon River ecosystem is a really cool display. It incorporates different rocks, driftwood, lush-green plants and thousands of fish choices. What's really neat is the diversification and appearances a shop can experiment with. They can be small (5 to 10 gallons) with small tetras and algae-eating shrimp or moderate with unique specimens. Larger displays ...

"Frankenfish”
By David Lass
Commercial breeders of ornamental fish have adopted many of the scientific breakthroughs in genetic manipulation, and have come up with quite a few fish that exist nowhere in nature.

The Yellow Foxface
By Patrick Donston
My favorite marine fish to stock in the shop is the yellow foxface (L. vulpinus). Mind you, it's not my favorite fish, but it's a great fish to have on hand for any shop (big or small) carrying marine livestock. Here's why. It's a beautifully colored fish. The body is mainly "lemon" yellow with a white head and black bands over the eyes. A long snout gives it ... More»

I wanted to describe conducting a job interview as being analogous to something in life. After I thought about it, I don't think it's like any social interaction at all.

The Nitrogen Cycle
By David Lass
While this may be old hat, I really believe that the Nitrogen Cycle cannot be over-emphasized in terms of its importance for successful aquariums. With new hobbyists, it is absolutely critical that they understand the process. To cover it quickly, the Nitrogen Cycle is the key to all life in an aquarium. Fish, decaying food, plants, etc., produce ammonia .

If you do not have a large section of your fish room devoted to live plants you are missing out on one of the fastest growing--and most profitable--segments of the aquatics business. Besides simply making a fish tank look better, live plants in a tank significantly improve the health of the fish. Healthy, fast-growing aquarium plants use ammonia, nitrites and .

QuickCure and Antibiotics

Medicating fish is an important and often controversial topic in the hobby and industry.

Oh, if wishing made it so. The reality of handling .
