Suggestions Please Alternative For A Mono

[Robbo851]

hi i recently saw monos at my lfs and thought they looked amazing however i do not nearly have a big enough tank or a brackish set up, however i am looking to add a new fish as one of my largest gouramis died (at least three years old dwarf) and i would like to add a similar fish to the mono but not brackish and not really get much bigger than 3-4 inchs, like an angel really but not as they are quite common and boring (sorry angel fans, i know a lot of people prob feel the same about gouramis)

my tank is 30 gallon sand with 2 dw gourami 2 honey gourami, 2 rams, a rainbow shark, a panda corie, and a flying fox. oh and some shrimp

more corys for your poor lonely panda cory.
but first i'd do the maths on your stocking, it sounds quite full up to me.

i count 22-24 inchs as the dw gouramis are now sadly both female (the male just died) the panda cory is the last survivor 3 i bought nearly two years ago one died within a month. the tank should be fine with another 3-4 inchs as its held two more corys and a male dw gourami aswell as a kuhli loach that has moved tanks. plus my 22-24 is generous as my rams are only an inch each but i counted them as 4 inchs for the both for fear of overstocking so one more fish is fine but thanks for the concern
