There is a maximum of 12 hours of daylight on the equator so that’s the maximum length of time that any aquarium containing tropical fish should be lit for.

Lots of our aquarium fish naturally inhabit soft water in the wild, including Cardinal tetras, Angelfish, Discus, Rams, Clown loach and Pearl gourami.

Few freshwater aquariums look more stunning than a planted tank. But its the first few steps of setting it up that can make the difference.

Set up a tropical tank and sooner or later you’ll want some cleaners. The tank light will cause the glass and decor to go green and detritus will start to build up in the gravel.

The oceans are unrivalled in their size and stability, and the corals we keep have evolved to that very, clean, pure, stable environment.

Bubble algae is a bottle green single-celled algae which forms jelly bean or round, marble-like shapes in the marine aquarium.

For the new reefkeeper, pH shouldn’t be made a priority. Once corals are added it is KH which has greater immediate importance because it drops quickly.

When cold weather is spreading across the UK it means ice and snow for many people. Pond ice is bad for fish for several reasons.

A pristine reef full of fish and corals looks idyllic, but alas many (very desirable,) fish species are there to eat corals or other fish and will do the same in the home aquarium.
