Reddit mentions of AmazonBasics 3-Shelf Adjustable, Heavy Duty Storage Shelving Unit (250 lbs loading capacity per shelf), Steel Organizer Wire Rack, Black (23.3L x 13.4W x 30H)

A lot of us made mistakes starting out, but what's important is we learn from our mistakes, take the advice given, and improve the quality of life for our little buddies. I also understand having too small a space for a really big tank, but a 5g or even a 5.5g is really NOT that big... as reference, I originally had 3.5g tanks (the TopFin Enchant) for my bois with lots of water quality maintenance, but recently switched over to 5.5g tanks (TopFin Essentials kit) which fit in the EXACT same places the old 3.5g tanks fit (after doing a bit of cleaning and moving of stuff that didn't actually need to be there on the tabletop or simply sliding them over a bit). The tanks are just a bit more longer, around 16 inches long, but if you think about it, that's really not that bad and will fit fine on most nightstands or side-tables / end-tables or whatnot. I actually wish I had made the switch sooner. I see a NOTICEABLE difference in how much more active my bettas are now with the slightly larger tanks, even though they were quite active in the 3.5g tanks.

Do keep in mind that a filled 5g tank will weigh around 40 lb, and a 5.5g will weigh around 45 lb, so whatever you choose to keep them on should be able to support that amount of weight without collapsing (don't let that discourage you from getting the proper size tank though, just make sure to find sturdy furniture to keep them on :) and all will be well).

Here's some possible sturdy yet small shelfs/tables which will fit a 5.5g tank:

https://www.amazon.com/AmazonBasics-3-Shelf-Shelving-Unit-Black/dp/B01LWP8AL2/ (it says each shelf can support up to 250 lb). The only thing I would add (although optional, but would provide better support for the tank) is a sturdy but thin plank of wood to the top shelf surface for the tank to sit on top.

https://www.amazon.com/dp/B07TLLSN5R/ (somewhat costly but looks great and sturdy)

• First thing first, you can hang all of your pot and pans from the ceiling. Something like:
  
• https://www.amazon.com/Sorbus-Rack-Ceiling-Hooks-Multi-Purpose/dp/B07D4RDCMB
  
• This would free up A LOT of cabinet space for storage of items that can't be hung.
  
  
  
• Next, You could use sticky hooks to hang your various range use utensils(Gloves, Spatulas, tongs, etc) above your range. Something like:
  
• https://www.amazon.com/Command-Decorate-eCommerce-packaging-GP001-9NA/dp/B0751RPD3V
  
• This would free up some additional drawer space.
  
  
  
• It looks like you are probably doing meal prep on the left side of the second picture. If so, your spices could go on the edge of the counter there.
  
• Your appliances could go in that thing all the way to the left in the second picture OR you could put a rack over to the right of your countertops in that first pic to hold them. Something like this:

It's just this shelf https://www.amazon.com/gp/product/B01LWP8AL2/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&th=1

with this case https://www.amazon.com/gp/product/B01N9JPTES/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

I had it sitting around with no use so decided to use it for my case.

Pssst... I'm using these as a tank stand. More industrial looking than a proper one, sure, but not made of particleboard and cheap as spit. They hold up to 250 lbs per shelf! And the black is, if I do say so myself, pretty handsome.

Return it and buy one if these.

Similar size, slightly cheaper, and WAY stronger.
