Hello, Frank Indiviglio here.  The world’s 30-35 freshwater sunfish species (Family Centrarchidae) range throughout Canada, the USA and Central America.  Although popular among European aquarists, sunfishes have been largely been neglected in American aquaculture. This is a shame, as all are colorful, interesting and active, and most adjust well to aquarium life. From the tiny Black-Banded Sunfish to the 39 inch long Largemouth Bass, there is something for everyone.  I’ve had the good fortune of working with a “sunnies” ranging from the tiny Black-Banded Sunfish to the massive Largemouth Bass, and would enjoy hearing from readers who have also come to know them, or wish to (please post below).

Obtaining Sunfishes

Although rarely offered in the pet trade, many species are easily collected via seine net or minnow trap (check state regulations).  While their diversity is greatest in the southeastern USA (my friend in Louisiana collected 8 species in the lake behind his house!), sunfishes can be found most everywhere in the USA. New York, where I reside, is home to 14 species.

Hi, Jose here. Last time, I blogged about keeping tropicals outside and how the sunlight, natural foods and warm temperatures can benefit tropical species. While the benefits are great, there are also some cautions to consider. This time I’d like to talk about some of the dangers and pests that may wreak havoc on our poor little fishies.

I was lucky not to have my pond visited by pests, but local stray cats, opossums, raccoons, snakes or predatory birds that may decide to visit your pond at any time.  Even bugs like dragonfly nymphs can prey on young and small fish. Ample water movement and surface ripples are usually enough to deter them, but more effort may be needed to deter larger predators. There are some easy ways that you can help to protect your fish while they enjoy their outdoor summer vacation. Personally, I would recommend the live plants. You can use floating foliage like water lilies, duck weed or hyacinths for cover and protection for your fish. Young fish will also hide in the roots and feed on the small bugs that live in the roots. Another solution is the use of pond netting. The netting can prevent many predators from snatching your fish out of the water. Not very aesthetic, but effective. Read More »

Hey there!  This week I wanted to talk about something a little different than my usual cichlid blog. I wanted to share some tips on how you can develop spectacular color on tropical fish in a way you may have never considered. 

A few years ago, we moved into a house that had a small pond in the front yard. It was one of those rigid, preformed round ponds about 15 inches deep with a  50 to 80 gallon capacity. We kept a few goldfish in there the first year. They grew and made it through the winter just fine as we expected.  Read More »

Few species of pond plants can be compared to the striking foliage and blossoms of the Sacred Lotus, Nelumbo nucifera. The Lotus is native to tropical Asia where it is deeply rooted in cultural symbolism, history, religion and legend. Its large, round leaves and spectacular pink, cream or white flowers are produced by long, buouyant, fibrous roots called rhizomes. The foliage and flowers stand tall above the water’s surface, while the rhizome runs in long strands through the mud or substrate. These plants and their hybrids are prized by pond and water garden enthusiasts and can be show-stopping if cultured and cared for properly. Read More »

With the wide range of body shapes and colors, it is hard to believe that all of the fish we call “goldfish” come from the same ancestor, a rather dull, silver/brown carp known as Carassius auratus. Almost two thousand years ago, Asian fisherman raised these fish in ponds for food, and soon the natural orange and yellow mutations of these fish caught the eye of Chinese royalty. Over time, the fish that we know as “goldfish” were selectively bred for specific traits and colors which would eventually become the varieties we see in fish stores today. Let me introduce you to some of the most popular “breeds” that have become aquarium mainstays over the past few hundred years.

Made for Outdoor Living

Comets – Perhaps the closest in appearance to the “natural” carp, Comets have longer fins than the common goldfish, and are often sold as “feeder fish”. They can be orange, white, silver, yellow or black. They get fairly large and are often sold for ponds rather than aquariums. The Sarasa Comet is a very popular variety whose coloration is a combination of pure white and deep red. Read More »
