Who Gives A Fish Forums

I'm deciding on the next care guides for fish I'll be writing. Currently, I'm working on part 3 of common freshwater fish and their care.

When writing about fish, I found it helpful to focus on species I've personally kept and bred. This approach allowed me to share firsthand experiences and unique insights, rather than relying on secondary sources. What about you - are there any particular favourites you'd like to share your knowledge on, or perhaps some lesser-known tips you've discovered through your own experiences?
