Are the 2 vastly different as in tank needs? Seem Leucs prefer a horizontal enclosure while Imitators prefers a vertical " tree" like enclosure?? Would Imitators do well in multiples?

I like both calls an being as Imitators are smaller I don't mind they're call is "smaller" I do like the bicolor look more too. However Imitators appear to be more reclusive?
