Indoor Cold Water Fish
COLD WATER FISH
We stock a variety of indoor cold water, or room temperature fish.
Most cold water fish do not stay small and so will require a big tank as they grow, 160L should be minimum for adult fancy goldfish
As cold water fish can eat and eat and eat they also produce a lot of waste, so big filters are required and a high level of maintenance on the tank is beneficial for the fish.
Orandas can grow up to 20 cm / 8 inches.
Water parameters of PH range 6.5-7.5, and temperatures of 17-24 Celsius / 65-75 °F.
Oranda are a peaceful cold water fish. They will mix well in small groups, or be fine on their own. They are a breed of goldfish that is characterised by the prominent bubble like hood on their head. The head growth or hood is a prominent growth on the top of their head or sometimes may encase the whole head except for the eyes and mouth.
There are a few different colours available, like the red oranda, red and white oranda, red and black oranda, blue oranda, chocolate oranda, calico oranda and the more well known red cap oranda.
They are greedy so will eat any food you put in the tank. They do require a food that will fit in their mouths, try not to feed any food that is too big for them, as they can get food stuck in their throats. Feeding them on the surface of the water can cause stomach problems, where they get air trapped in their stomach. This will cause them to have a bloated stomach and float upside down. Sinking the food can be better for them. They will eat flake, small pellets, and granular foods, plus a treat of freeze dried, frozen or live foods.
Best Feed once a day at the most, but they can go a few days without food.

Pearl scales fish enjoy pellets or flakes in their diet. They will eat on the surface of the water or of the bottom of the tank on the gravel.
But we do recommend sinking the food as pearl scales can get air trapped in their already fat bellies.

Black moors are lovely peaceful tank mates in cold water set ups. They are very slow swimming fish so should not be mixed with quick moving fish as they would struggle getting to the food before the others eat it.

They eat flake foods, small pellets or granular foods. Sinking their food is best as if they eat on the surface they can gulp in air, and cause stomach bloat. This will make them swim upside down and cause them stress.

The head growth fully covers the head cheeks and gill plates of the fish. They also have a short deep body and the body is relatively straight, with evenly arched backs with no dorsal fin.
They can sometimes be a little bossy so it’s best not to mix with slow moving fish.

The bubble eye is a peaceful cold water fish. They are a small variety of fancy goldfish with upward pointing eyes, that are accompanied by two large fluid filled sacks. They are a dorsal less fish.
The bubbles are fragile and can be punctured easily, so you do have to be very careful with them. They are best mixed with each other, or with non aggressive slow moving cold water fish. The bubble eye is not a strong swimming fish mainly due to their bubble eyes.
They will eat flake, mini granular, and pellet foods. Also a mix of freeze dried, frozen, or live foods is always a good treat for them. On a bubble eye goldfish you will notice their eyes are pointing up as their bubbles are underneath their eyes, so feeding floating food may be best. They can still forage in the gravel for food but if they catch the bubble of a sharp piece of gravel this can pop the bubble.
They are only small fish so only require small food and just feeding them once a day at the most is best.

Ryukin are a form of fancy goldfish that are expected to reach 15cm.

Water temperature should not drop below 18c, and will do well up to 22c.
Characterised by a prominent arch behind the head, and a triangular body shape with long flowing fins. They are offered in a variety of forms, with a popular form being the calico variety which is similar to a shubunkins colour.
They’re hardy fish, but produce a lot of waste meaning they need plenty of filtration and a suitably large tank for adults.
Food is always well received, and we always recommend the use of sinking foods to avoid potential blockages of air. Frozen and live foods are great to use as a treat, but the bulk of the diet should consist of dedicated fancy goldfish foods.
Daily feeding, with live and frozen foods limited to 2-3 times per week is ideal.
Our recommended food for these are;
King british sinking goldfish pellets
