How many tanks do you have?

[i cant think]

TLDR: How many tanks do you have running? And what do you have them set up as?

I’m intrigued on this as I have just set up my 4th tank (a 3rd Nano system, just under 20G). However what I’m finding is that (and this is possibly due to having 4 other display systems in my LFS) I got bored quite easily when I had 2 tanks set up as mixed reefs, it just got to a point they looked boring as one was effectively a mirror just in a smaller tank than my 5 foot.
So, here are my 4 tanks currently, from smallest to largest!
1. My Macroalgae nano - 48l (12G), set up in February 2025!

2. Set up last night, my 78l (20G) nano. Still wondering what to do with it.

3. My 100l (25G) nano, initially a reef tank, now running as a frag tank, this was set up back in August/September 2022.

And finally, my big boy tank, my 5 foot 700l (180G) tank! Ignore the PAR readings - I don’t have many up to date FTSs of this system and my 100l nano.

As you can see, I have set them all up differently to each other, with a Macroalgae & Gorgonian reef, Frag Tank and a full Mixed Reef (with some arguably riskier RSWC Fish in).

Turn the new tank into quarantine? It really is a smart thing to have around…

Here’s my quarantine currently; used fluval edge 15g AIO… tank number 4, 5, or 6; depending on who’s counting, and what counts!

I voted 4 but if you count the hospital tank, it’s 5! lol

450gal: acro dominant, angels & tangs
150gal: mixed
90gal: mixed
25gal: anemone

All tanks are BB, except the Haddoni anemone tank. 3 of 4 tanks run a carx and 2 tanks got kalk.

It’s fun balancing all 4 tanks! ;)

That gorgonian tank is absolutely amazing!!
