Where do Betta splendens actually live? (opens the original)
Read excerpt
The first time I visited Thailand, I was immediately struck by the sheer biodiversity in every body of water. I went there on holiday, but as an aquarist, it was impossible to resist looking into every pond, stream, and flooded field I came across. At the time, I had not done any research on Thailand’s native fish species or their habitats, nor did I have any underwater filming equipment with me. It quickly became clear that I had to return, this time properly prepared. I eventually decided that

Over the last few articles in this beginner reefkeeping series, we’ve covered some of the essential pieces of equipment you need: But how do you actually make the tank itself look good? Well, laying out the décor can be one of the most fun parts of setting up a reef tank, and it allows you to bring your creativity to the forefront.

I can trace my interest in fish back to around 1962, when I was at primary school. There was a fish tank in the school foyer, the old-fashioned glass and putty type within an angle iron frame. I would often spend time in front of the tank during lunchtime. At the time, I had no idea what the inhabitants were, but thinking back now, I know they were neon tetras, guppies and small angelfish. I can also vividly picture the tank being filled with Vallisneria. Fast forward to my early 20s, and my the
Bristlenose catfish: the hardworking Ancistrus (opens the original)
Read excerpt
Algae eaters. Every fishkeeper has likely asked for one from their local fish shop at some point during their time in the hobby. Previously, you'd walk around shops and see tanks filled with common plecos, pictured below, which is a name that has been used for several species. Fishkeepers would happily take them home, expecting the fish to happily graze on algae and not cause any issues. All photos by Shutterstock unless otherwise stated However, after taking home a common pleco, algae is no lon
