Fish Skin

Surgical excision of skin folds from the head of a goldfish

A great professional article on wen trimming:

The area in purple is the wen which is composed of hyperplasia of epidermis and increased number of mucous cells"  The dark area is melanin bordering the "increased deposition of adipose tissue in the subcutaneous layer" but the wen itself is not adipose or fat but rather hyperplastic (over grown and expanded) epidermis and mucous cells.  The epidermis is the skin on top of and into which scales are embedded.

Resetting a tank

I'm resetting this tank to put the Oishi herd in. Using potassium permanganate in a pump sprayer to sterilize and wash everything down. The tank is 72x48x18 for about 270 gallons. It is on the commercial dirty fish system but I'll run it in isolation as a flow through.

Oishi 2006

It's turning into a cold November. This trio of japanese born Oishi 2006 fish is spending the fall in a 240 gallon fiberglass pond. They have a large bowl filter and tons of hornwort in the tank. The bottom is sandy and their diet is largely earthworms and Daphnia.

I love playing with goldfish in the rain. Removed the fading duckweed and did a large water change.

The smaller female had a large ulcer/fungal infection on the side but baytril injections and potassium permanganate did the trick.

Blue belly tamasaba

From the web (Japanese)

Rare Japanese goldfish arrive in the UK

From: Practical Fishkeeping

A single tailed red and white goldfish called Tamasaba sabao has been imported into the UK.
Looking like a cross between a Sarasa comet and a Ryukin, these large growing hardy goldfish are colourful and suitable for outdoor ponds.

The supplier is called Aquadistri, a Dutch fish, plant and dry goods wholesaler with a Koi supplier in Niigata, Japan, called Ornafish.

Along with regular supply of Japanese Ko,i their farm produced 180 Tamasaba sabao, 150 of which went to their Holland premises and 30 of which came to the UK. The actual 180 goldfish can be seen on the video below.


Created by Koi breeders
"The Tamasaba, also known as a Sabao, is a rare type of Japanese goldfish, with a body shape similar to that of the Ryukin," says Aquadistri. "They have a very long, flowing, single tail.

"Tamasaba is the result of a cross between the cold hardy, singletail Syounai and Ryukin and was created and bred by Koi breeders in the Niigata area of Japan.

"The Tamasaba is bred in red and white, and mixes well with Koi. They are cold water adapted and are highly treasured in Japan."

The fish are large at 18-20cm/7-8" including their long tails, with very strong red and white colouration. Males and females can easily be picked out.

The supplier believes that they are the only 30 in the country and they are currently in quarantine, fresh from the mud ponds in Japan. They are being fed a diet of high quality Hikari foods.

Aquadistri do not sell to the public, although they supply most of the retailers in the UK with plants, frozen foods, or dry goods, so fish could be bought via a shop.

At their premises in Sandy, Bedfordshire, they have cash and carry facilities whereby retailers can visit, inspect and hand pick fish, and they have excellent biosecurity and health protocols in place.

They had some superb Chinese goldfish when we visited, too.

Practical Fishkeeping Magazine photographed this rare fish and we will publish an in-depth article in a future issue.
