IMO you can keep the tiger barbs if you lose all other mid/top level fish.
Keep one shark (redtail or rainbow).
Go for something like:
25 tiger barbs
1 rainbow shark
6-8 cories
Maybe one or a pair of SMALL pleco/ancistrus
Also get some plants if you can - they'll help keep ammonia and nitrates down
