1Silver/Bala Shark? Should reach ~40cm, needs a big group to reduce skittish behaviour, 9x3x3 absolute minimum, ideally a longer tank like a 12-footer (which of course we all have
) is better.
1 Clown Loach? Again, need a big group (just like Bala Sharks, not just 6), minimum 6x2x2 tropical, high current setup.
If kept correctly 1 foot is no problem, google "Marge the Clown Loach."
2 Glass Catfish? Known to pine when kept in small numbers, definitely needs a 10+ group, very sensitive to water chemistry changes.
4 harlequin rasbora? Another schooling fish, needs some more to boost numbers, at least two more.
1 pakistan loach? Another chooling fish, needs another five conspecifics.
2 boesman rainbow fish? Another schooling fish, two females per male if a mixed sex group, needs four four adding at least.
1 climbing perch? Almost certainly going to enjoy the live lunch you provide aka the 5 guppies.
2 plecs? Which of the many species are these? Common or Sailfins perhaps that reach ~40/60cm and are massive drains on filter bacteria?
1 elephant fish? Awful choice in this setup, needs very carefully selected tankmates that are calm feeders and calm by nature eg. African Butterfly Fish, Leopard Bushfish etc.
