160L overstocked!

[jordan511]

Hi, I have recently taken over a 160L tank from a family member. It's been running about a year, everything in it doing great, but is very overstocked. I have been testing regularly, weekly water changes and everything is actually running perfectly. The filter is probably what's helping as is capable for up to 300L. Plenty of live rock and few corals. What problems am I likely to encounter with this stock list?

Pistol shrimp and goby pair
Fairy wrasse
Cleaner wrasse
X6 green chrommis
X2 common clowns
X2 Bengaii cardinals
X4 hermit crabs
X1 crab unknown
Cleaner shrimp

I'm assuming that the bengaii, clowns and green chrommis may out grow the tank?
I know Cleaner wrasse can be difficult but this one has been in there for a few months and no issues, eating well.
Hoping to upgrade the tank at some point but won't be able to go any bigger than around 230L

My reading suggests that the 6 green chromis will become either one or two in time.

The clowns and cardinals would like a bigger tank but they don't grow that fast, ime.

If they are not fighting now amongst their tank mates, they may be fine until they do grow for a year of two, and then you will know how it went amongst the fishes you have.

Thanks, appreciated.
I believe the 6 chrommis were the 1st fish in there so hopefully after this amount of time will be OK
