Having a marine aquarium of whatever type is a wonderful individual hobby. It’s also really good to have someone to talk to about it, exchanging ideas, opinions and stories.
The very best way is to have local friends who are aquarists. They ideally are marine enthusiasts, but could be keepers of brackish or fresh water systems.
If there aren’t any friends about who are also aquarists, there’s sometimes a club or society where sitting and gossiping over a coffee or something a little stronger can take place.
Then of course there’s the communication channel available to very nearly everyone, the internet. There’s a wealth of information available. However, searching for specifics can sometimes be quite long winded so there’s an alternative, and that is the forum where questions can be asked. There’s one on this website.
There are plenty of forums available and finding one that is suitable and liked is great. One or two deal in advanced subjects, but the majority have specific discussion areas for various topics.
Here are some forums listed, with thanks to ‘Muzzy’s Reef’.
