75g stocking?

Gernader · May 8, 2020

I just upgraded my tank to a 75g with 30g sump in total of 105g. I’m wondering what reef safe fish can I add with my current livestock?

I’m thinking of a small yellow tang (I know I need to rehome it in a couple of years). What other fish can I get? Wrasses or something else?

Current Livestock:
- 1 Ocellaris Clown
- 1 Ruby Long Fin Fairy Wrasse
- 1 Banggai Cardinal
- Skunk Cleaner Shrimp
- Fire Shrimp

Thanks in advance!

Generally speaking, from my experience, you probably get away with 8-12 fish total smaller fish in a 75 gallon display.

Me personally, I’d add 5 blue/green chromis and throw in another clown. I also have always enjoyed a bicolor blenny. They’ve got great personality and will eat algae too.

The 30 gallon sump and total water volume makes no difference. Stocking is all about what the display can handle.

I used to have chromis before, but I try to avoid them due to their diseases and sometimes, they do not survive in quarantine based on my experience and a couple of LFS too. I had two clownfish but I took one out due to the aggression lol. I do like the bicolor blenny though. And for the water volume, I thought it would be helpful to determine the bioload or something.

For the most part your display should be able to handle nearly all of your bioload’s filtration needs. That is, unless you have a minimalist rock-scape and are bare-bottom.

I have no experience with anthias, but a small group of 3-5 flame anthias might be a nice addition. I’m planning of putting 9 of these guys in the 115 gallon tank I’m setting up. I believe a 75 gallon tank is the minimum recommended size of tank. They do require several feedings per day, so an auto feeder is something you should look into if you go that route.

Well, I have a thin layer of coarse sand, but I have many rocks in there. I do have an auto feeder on hand that I can use for Anthias.

This is my tank:
