Hello Betta friends!! I'm back finally after a very long hiatus. Most of you probably don't remember me, but that's alright.
I've been heavily debating getting another Betta or moving on to slightly more complex setups.

After some careful budgeting and measuring of the time involved, I've decided to go with a Green Spotted Puffer.
Some of you may remember that I had a GSP before (he ended up getting re-homed because I went out of country). I've since learned a good deal about how to better care for a GSP and I'd like to try again.
GREEN SPOTTED PUFFER.
Why: Because they're cute, they're full of personality and I happen to like aggressive fish. Also, this will be a perfect segue into keeping marine fish.
My ideal setup:
(FOWLR system)
Tank: 20 gallon long (for wandering/swimming room)
Substrate: Crushed coral
Live rocks (with lots of hidey holes; probably about 15-25 lbs. worth)
Equipment: Powerhead, HOB skimmer
Lighting: Coralife 50/50 50% Natural Daylight 6,000 K Fluorescent Bulbs
Diet:
Frozen bloodworms, clams, snails, shrimp, etc.
I'm not sure if I'll need more filtration than what I've got planned now... and I'll be doing a simple drip-acclimation method over the course of 5 hours to ensure he's doing alright. And I'll cycle my tank first, of course. :)
I expect my salinity to be right at 1.020.
Suggestions and comments are welcome!!
