It’s completely normal for budding fish keeping to dip their toes in the water with a new hobby, but once you’re skills have improved what then?

This is where it get’s interesting and the hobby get’s more difficult. Some people move onto marine fish to get those beautifully coloured species while others go a less trodden path. Having a tank with most of the fish pictured in this thread would certainly give you a conversation starter with any visitors who look at your tank.

Lungfish and Gars

Lungfish are thought to be related to early amphibian species.  Unlike most fish, they actually have lungs, allowing them to breath air.  These fish are hardy, if not the most easy on the eye.  They can survive in tanks with little or no aeration.

Gars do not have lungs, but have an incredibly thin, long body shape.  They are more difficult to keep than lungfish, but their quick movements and unique predatory behaviors make them attractive to more experienced hobbyists.

Certainly a strange and unique species!
