The usual 'first fish' for a new fish-keeper is the goldfish. Unfortunately this is often the 'first mistake' as well. There are a number of cold water fish much more suited to aquarium life and easier to care for than the goldfish.

Whats wrong with Goldfish?
Goldfish, contrary to mainstream belief are not at all suited to small aquaria - they grow too large (35cm 14"), they are boisterous, messy feeders and will eat plants. How about the fancy varieties? Well, these deformed fish come with a whole host of problems and most end up floating/sinking with swim-bladder difficulties or damaging themselves by getting stuck/scraped/torn on benign aquarium objects .

Coldwater tanks All is not lost however; the conditions in suitable unheated aquaria are perfect for a whole host of fish that are easily to keep. Firstly, lets define 'suitable aquaria' - anything less than 15litres capacity (30x23x23cm 12x9x9") is best used as a vase, to collect drips from leaky roofs, or left to the experts. Very few fish can be properly kept in an enclosure this small without considerable knowledge of water quality and a good idea of the fish's natural environment. An aquarium measuring 60cm (2 foot) would be a better starting point and will cost little more than an aquarium half the size. Filtration is also an absolute must; no fish can be kept properly without a good stress-free waste removal system .

What we stock for cold water tanks .
These temperate fish come from areas in nature that are either sub-tropical or experience fluctuating temperatures throughout the year such as high altitude streams or waterways fed by meltwater. The fluctuating conditions in these areas have caused the fish to develop a tolerant and hardy nature, making them ideal fish for smaller aquaria or for new fish-keepers .

White Cloud Minnows and Danios
The smallest of the common temperate fish are the popular white-cloud mountain minnows Tanichthys albonubes and the zebra or leopard danios Brachydanio rerio both these fish are hardy shoaling species and should be kept in groups of six or more. These two fish will constantly zoom around the aquarium so are best given plenty of open swimming space with hiding spots in plants and decor around the edges of the aquarium. Because they are so active they are best kept with other active fish that will not become stressed by constant movement.



Barbs
Thankfully many temperate fish fall into this category, most notably some of the barb family including Rosy Barbs Puntius conchonius, Golden Barbs Puntius semifasciolatus, Odessa Barbs Puntius ticto, and the slightly larger arulius barb Puntius arulius. Rosy, Golden, and Odessa Barbs will all grow to a few inches and will develop colourful and distinctive markings .

Scavengers
For the lower reaches of the aquarium, the popular Bronze, Peppered and Albino Corydoras sp. are well suited to cooler waters providing the substrate has no sharp or jagged elements. These fish are best kept in groups and they will require their own food source from sinking pellets or frozen/live foods. The Port-Hoplo Catfish Megalechis thoracata, syn: Hoplosternum thoracatum can also be kept in temperate conditions and there are few fish with as much character as this one. Because the fish has very bad eyesight and depends on its other senses to find food it will simply charge around the aquarium investigating everything it finds, often in a comical manner. These active catfish can reach 15cm (6") so a larger tank is essential .

What Lizzy said.

It's been an exciting few months after purchasing our first tank! The guys at The Aquatic Store have been brilliant with their advice, helping us choose the best fish for the tank we bought, and making sure we had a good amount of each species for them to shoal happily. We wanted to have live plants, and create the best environment we could for the fish. They're really healthy, and so beautiful! I'm learning so much and loving it!
