Predators for a 20 gallon

Sorry if this has been asked before, but is there any highly aggressive predatory fish that would do fine in a 20gallon? Any decent sized aggressive cichlid suitable for this size of tank?

defiantly this

Is this a 20 long or a 20 High?

maybe a single jewel cichlid?
I do like the exodons idea too

As for a cichlid I'd get a convict.
Otherwise.. snakeheads are legal in Scotland right? you might try a small one like bleheri.

Crenicichla Regani are predatory not overly so and would work in a 20L. Very neat dwarf pike.

Maybe a couple smaller species of rift lake cichlids, or as someone else stated exodons. Another personal favorite of mine that would be ok in a 20g is a blue acara. They are equivelent temperment wise to a convict, but much more appealing to the eyes imo..

Aggressive and predatory are not always linked. The pike is predatory but not so aggressive. The convict is aggressive but not predatory. The exodons are clearly both, but 4 is probably not enough - you will soon be down to one.

Assuming your "predatory" criteria relates to a desire to observe feeding behavior, I'd go for the dwarf pike - great personality, great appearance. But I am partial to cichlids...
