Do you consider my current setup overstocked?
Tank Details:

  • Size: 60-gallon (90 × 45 × 45 cm)
  • Type: Mixed Reef (including Acropora millepora), with nutrients kept well under control.
In the Korean reefing community, this is generally considered acceptable (and I agree). In fact, I'm planning to finish off my livestock list by adding one 12cm Regal Angel. However, I'm curious if saltwater hobbyists in the US would view this as overstocked.
Current Livestock:
  • Pair of Percula Clownfish (7 cm & 4 cm)
  • Blue Tang (6 cm)
  • Yellow-brown Scopas Tang (8 cm)
  • Rock Blenny (7 cm)
  • Coral Cat Shark (17 cm)
  • Flameback Angelfish (4 cm)
  • Flame Angelfish (6 cm)
I'd love to hear your thoughts!

I copied and pasted your post into Google translate, and I got this in return:
"Do you think the current setup is overstocked?

Tank Details:

Size: 60 Gallons (90 × 45 × 45 cm)

Type: Mixed Reef (including Acropora millepora), well-nutrition controlled.

In the Korean reef community, this is generally considered acceptable (and I agree). In fact, I plan to finalize the stocking list by adding a 12 cm Regal Angelfish. However, I wonder if saltwater enthusiasts in the US would view this as overstocking.

Current Stock:

A pair of Percula clownfish (7 cm & 4 cm)

Blue Tang (6 cm)

Tawny Scopas Tang (8 cm)

Rock Blenni (7 cm)

Coral Cat Shark (17 cm)

Flameback Angelfish (4 cm)

Flame Angelfish (6 cm)

I’d love to hear your thoughts!"

To me, your 90 cm tank seems quite small for the fish you have, such as the Tangs and the Cat Shark. The Cat Shark alone should be in a very, very large tank, at least 200 gallons plus, in my humble opinion. So yes, I would say that you're overstocked no mater where you live 🙂

I hope this helps 🙂

"Oops, I accidentally posted this in Korean. Sorry about that!"
 
"To be honest, I know this tank won't be big enough once the shark fully grows (it's currently a juvenile at 17 cm, so I think it's fine for now). Once it passes 30 cm, I plan to rehome it to someone with a better environment."
 
both tangs can reach a size of 8-9 (20-22cm) inches. The shark about 28inchs (70cm) +-

A tank that is 36” (90cm) is too small if you ask me. These fish can grow fast. A buddy of mine got a blue tang (hippo) and it went from 1.75” (4.5cm) +- to 3-4 inches (7.5-10.1cm) +- in a 3-4 months.

My personal experience with my purple tang being I actually measured him.

2” (5cm) last June-July don’t recall the exact month, it’s now 5.5” (14 cm). Fish can grow fast also dependent on feeding, and what type of food.
 
Not about the amount of fish but about the types of fish. These fish will quickly outgrow the 60 gallon. Almost every one of those fish is recommended to be in larger tanks. Blue tang should be 150 gallon, the cat shark should be 300 gallons... we have to respect the animals that we keep. IMO

It is overstocked.)
 
I would ditch the tangs and the shark. I see too many people who say, "It is fine for now; I'll upgrade my tank or get rid of the fish when they get too big," and never actually do this.
