So I had an unexpected leave and now I'm back

[Puto Swerve]

Came back and my tank was empty because my fish died ):
I'm glad to see that the guild didn't revoke my membership though! 3nodding

Anyways, I used to own a pure memphis tank and I was wondering
if you guys think it'd be a good idea for me to fill my tank with watermeats now;
are they still a popular batch of fish?  

[Blood Pop]

We wouldn't remove someone's membership just because they don't have a tank! That'd be silly. :3

From my observations, Watermeats don't seem to be overly popular anymore. At least, I never see full/mostly full Watermeat tanks get many players nowadays.
The most popular fish now are Dolphins/Irrawaddy Dolphins, Airsharks, Stone Coatls, and some of the other Mini Monsters.
You could still try making a full Watermeat tank and see what happens, but it could be difficult for you to profit from it. :c
