Tbh I think MFK is dying.
I was very active on the forum in 2011-2012, and this place is literally a ghost town compared to how it used to be.
But I am currently active on another forum/board (won't name it here), and membership there has spiked up a ton over the past year or so. From about 50,000 to almost 100,000 members. It is way more active and I think more indicative of the current trend in fish keeping.
That current trend is for smaller, planted aquariums. Shrimp seem to be way more popular than they were, and people tend to be way more envious of beautiful 40 gallon tanks than 300 gallons that are filled with monster fish.
The hobby is strong, but it has shifted, and unfortunately, this site does not seem to be able to keep up.
