When to stop adding fish?

[JeepTj]

135 gallon, 30 gallon sump.
bites tongue here ….. haven't don't a water change since I swapped everything from my 60 gallon tank , over 3 ish months ago.. but dang im adding a lot more top off water since DIY ATS .. and the sicce syncra pro 7000 (regulated )

my biggest concern I over did it.. but tank still looks empty lol

currently have
1 Sailfin tang (6~ inches right now)
1 dory 3~ inches
1 powder brown 3~ inches and swims around with dory
1 copperbanded butterfly 3~ inches right now
1 yellow tail angel 3~ inches
1 coral beauty just a bit smaller then the yellow tail
2 juvi percs tiny
2 mature mated occ clowns typical
1 blue chromis small , only one that survived the attack of my original maroon clowns
1 male lyretail, females didn't survive
4 bangaii Cardinals
1 Yellow Watchman goby tiny rarely see him unless food time consider part of cleanup crew now
1 Milk Goby fair size compared to the watchman
cleaner shrimp
pistol shrimp
coral banded shrimp

levels are good according to my salifert test kits and verified at local ma and pa fish store... I do add trace elements , and such anemone's are happy and thriving so im not concerned atm just thinking long term as some of these fish mature and grow much larger .. forgot to think ahead ..

3 tangs in 135 gallon is already a crowd IMO so I would be careful about adding anymore fish as tangs can become pretty aggressive especially once established.

From a biofilter perspective, I don’t think there’s an issue, these days we can run very crowded tanks without major problems. Your problem will be compatibility, stress etc.

I agree with emdereef, you are already overstocked for that size tank and will probably end up having to rehome some of those tangs down the road due to aggression.

yea figured as much, and was warned about the aggression, figured try anyway, they seem happy keep them well feed yet to see any aggression other then occasional chase of the 2 angels .. otherwise i can feed right out of my hand, the sailfin especially he's a big baby..lol , worst fish i had was my Scopus for aggression, but unfortunately he got what looked like HLLE as was agreed here on forums but in quarantine he passed on just would not eat no matter what i tried ..

the 2 juvi percs will be removed once warranty comes back for my daughter's tank.. one of the corner seams split, finally got warranty approved took LONG time.. even them tho is no agression from the established mature pair just the occasional get away from my nem if they get to close.

not looking at adding any more fish , just time to landscape now and work that way on other living things

impulse buying.... has to stop Hahaha just bought a Old English SheepDog .. that wasn't cheap either :O
