What is the single easiest tropical fish to keep?

The platy is hard to beat — hardy, colourful, peaceful, undemanding about water and cheap. Zebra danios and white cloud minnows are almost as forgiving and cope with cooler rooms. Any of these in a cycled, heated tank gives a beginner a very high chance of success.

How much do beginner fish cost in the UK?

Most beginner tropical fish start at about £2-£4 each, so stocking a first community tank is inexpensive. Budget more for the tank, heater and filter than for the fish. Prices on this page are live: what you see is what's in stock today.

How many fish should a beginner start with?

Just a few hardy fish at first, added to a fully cycled tank, then build up slowly over a month or two. A young filter can't process the waste of a full stock list at once, and overstocking early causes the ammonia spikes that kill beginner fish. Patience in month one pays off for years.

What do beginners most often get wrong?

Skipping the tank cycle, adding too many fish too fast, and choosing the wrong species — a common pleco that grows huge, a shoaling fish bought in twos, or an aggressive fish in a peaceful tank. Cycle first, stock slowly, and pick hardy community species, and most beginner problems simply don't happen.

Is it safe to buy beginner fish online?

Yes. The forgiving species we recommend for beginners also travel well — bagged in oxygen-charged water inside an insulated box, carried midweek by a licensed live-animal courier so they never sit over a weekend. Every order carries our photo-proof live arrival guarantee.
