Is my tank overstocked?

[Hotelbravo]

Hello, i have a 300 gallon mixed reef, i am wondering if i am at or past my stocking limits in your opinions.

Currently i have:
1 large purple tang
1 XXL Niger triger
1 XL Naso tang
1 XL Sailfin tang
1 medium kole tang
1 XL Unicorn tang
1 large fox face
1 medium spotted rabbitfish
1 medium blue hippo tang
1 large valentini puffer
8 clownfish (with their own sets of anemones)
2 Spotted Snake Eels (around 3 feet long)
1 spotted mandarin goby
25ish Green chromis

The 2 large eels spend 99.99% of their time inside their multi-chamber pvc tunnel system that is under the sand.

At, and past unless you do a lot of water changes or have a crazy filtration system.

PIc of this tank, and information on your filtration & normal parameter levels might help tune folks replies.

Great assemblage , btw!

Yes probably a bit overstocked. Up your filtration and maintenance is you are worried. If water quality is good and the fish aren't killing eachother you are probably ok. Once carrying capacity is exceeded organisms compete for limited space, habitat and food.

I have a 75 gallon sump and a 40 gallon refugium all plumbed together so total water volume is around 400 gallons, i do monthly water changes of 100 gallons and only coral that i cant seem to keep are SPS.

what are your parameters?
SPS don’t love overstocked tanks, they prefer the lower stocked tanks or the low bio load fish tanks.
LPS and Softies all love dirty water and most of the time the dirtier the better for them (especially softies)
