Need advice on small fishes for cleaning crew

[Shadow]

Can anyone advice me which small fishes are good for cleaning crew? Need something than can eat leftover food on the gravel. I was thinking of C.habrosus or C.hastatus but can't seems to find it.

Hmm... I am not sure if C. hastatus actually cleans up food from the gravel as efficiently as the others. C. hastatus, unlike most cories, mostly hover and hang around in mid-water level of the tank. For me, C. hastatus is too cute to be used as cleaning crews.

Otocinclus sp., Parotocinclus sp. or various loaches can do the job.
