20g + 10g sump...how many fish can i add?

[fr3n0z]

Hi guys, i would like some help to see if i am overstocking.

I have a 20g display (fish, sps, lps, soft) with a 10g sump with rocks and chaeto. Mixed reef.

I would like to add 1 mandarin, 1 six line wrasse and a mithrax in the hope it will take care of eventual valonia (i already have valonia in the refugium, so the mithrax it will go in sump to start with). You think Is this too much?


At the moment i have 1 amboniensis, 1 thor, 1 okinawae, 2 clown, 1 firefish, 1 BTA. No3 and PO4 are often bottomed out (i dose if needed sodium nitrate and sodium phosphate). I run skimmer, chaeto, carbon h24, filter roll, i feed lightly. Pod are present in display and in sump, mandarin is trained to eat also frozen. Tank is running for little over a year.

i dont think any of those fish would be good for a 20g , i got a 60g and wouldnt attempt a mandarin

Mature tank, doesn’t appear overstocked to me.
If nutrients are stable, your good.
Since your Mandarin is not reliant on pods that’s ok.
Six line has a hit/miss record, some find them model citizens, some find them terrors.

mandarin was my first choice, pod population is fairly good and is frozen trained.

Having a problem finding some other inabitant that is lively and not a possible terror. I've got the firefish and is super shy, it hides all the time (clown are on their own and in the opposite side of the tank, so no stress problem) the okinawae is top notch, not lively but it does what it should do. Stay in the front hopping from coral to coral or lying mostly on the pavona.

I was looking at gramma loreto, dottybacks, etc but in the end i think the six line is the safest between them.

Goby's and blenny's i'm scared that they hide all the time aswell. Nematoptera (another option) i'm scared is a bit too still and being nocturnal it will hide aswell.
