Tropical Fish

Goldfish

 

Our offer in ornamental fish is immense. Fish of all colours, shapes and sizes inhabit our aquarium.

In nature, most ornamental fish live and gather in groups. Therefore we recommend groups of at leased 6-8 per species. In doing so, the fish are better kept according to their natural requirements and also more attractive.

It is always an advantage to combine fish that stay at different water layers. For example: Guppies, gouramis, neon/cardinal tetras and catfish, or platies, barbs, dwarf cichlids and catfish. Introduce some algae-eating fish, as they scrape off algae from the inside aquarium glass, stones, gravel and plant leaves.

When buying fish make sure that you only select healthy fish. Their fins should be open and erect and not shredded (Fin & Tail Rot). Should be free of cotton like growths (Fungus), "crystal like" spots (Ich) or ulcers. Make sure the fish is swimming around actively and not laying on the bottom of the tank.

The most common group of community fish is the livebearers. Most of them are ovoviviparous i.e. they are fertilised internally by males, and the eggs hatch inside the female to produce fully formed babies.

Male livebearers can usually be identified by their gonopodium. This is a modification of the anal fin into a pointed flat fin and is absent in females.

Guppies, Platies, Mollies and Swordtails, produce a "packet" of sperm called "Spermatozeugmata". When the female is fertilised with spermatozeugmata she can store the sperm and use it to fertilise successive batches of ripening eggs. This is why females can still have babies even if you buy only females and no males.
