I'll just say that I've had young Sterbai and Trilineatus in my tank with a Bolivian Ram and an Angel for almost a year and never had any issues.
(The OP has a community tank with a couple of dwarf cichlids rather than a cichlid tank).
Thanks Jamepsss. Hopefully i'll not be having any issues as well. I only see territorial aggression among the ram, apisto and pearl gourami and they havent bothered the corys at all even though they are scavenging right beside the dwarf cichlids during feeding.
By dwarf cichlid do you mean the bolivian ram??
Don't know if they count as dwarf cories but i've kept Juvinile panda corydora with dwarf cichlids before without a single iota of worry. Cichlids get a bit shovvy at feeding time, but the corydora's seem to take it in their stride.
Yes FF, i meant both the bolivian ram and the apistogramma macmasteri as well. Think panda's are dwarf as well, but in my case my cories are as dwarf as they can get

. They are settling in nicely however, swimming in the middle of the tank, resting on the leaves and scavenging the bottom during feeding. Although it's very little time of less than a week i had them, there has been no aggression towards the cories.
BTW, in terms of feeding, shall i get the usual bottom feeder food for the cories, as i currently feed flakes, pellets, veggie flakes and daphnia over the weekend. Do you think they will be fine with this food or it's better to get some bottom feeder food and stick it to the glass in the middle levels for the cories to munch on them.
Also, i wish i could have had like 20 of these c.hastatus (instead of guppies) as in my limited experience, these are the best shoalers i have seen (probably 50% better than harlequin rasbora).

Thanks
