im affraid to say that your tank is no way big enough for those fish
2 oscars - the tanks not big enough for 2 adult oscars
4 tinfoil barbs - the same applies
2 plecos 1 12inches - sounds like a common or gibbi pleco and should be fine
other 3 inches - depending on what it is should be fine
3 clown loach - get big but should be fine
2 bala sharks - possibly dont get too big but need more room as they are very active fish
2 ruby sharks - no issues with size here but they will both need a teritory to patrol
are your fish juvis or adults?
im sorry to be the one to tell you but someone will have and the sooner the better really.
then they obviously had no consideration into their fishes wellfare. oscars can grow up to 12-14 inches and can be very nasty fish especially with other oscars. they are also very messy fish with their waste and the way they eat so to house 5 oscars in a 5ft tank would have needed very large amounts of filtration..... some oscars will get along with each other especially if grown up together but 5 in a tank of that size is ridiculous. they would have had no where to retreat and get away from it all and i imagine they must have been very stressed out..... i am amazed they lived for 18 years
6.5x2x2 with 1 oscar.
if you want to keep all of those fish i would get an 8x3x3 minimum. but more realistically rehome some of the bigger fish and keep what you have. you could get away with from your stocking
if looked after and fed correctly they can grow about an inch per month so they wont stay the cute little things they are today for long.
