well i'm not good at converting size to gallons but i hope that is a big tank

cause your lookin' at 54" of fish (only 50" if your lucky and the bala or "silver shark" only grows to be 10")
also take into consideration that these fish have different temperments
like the penguins and platy are very peaceful community fish,
and the barbs are semi-aggressive little a-holes
then you have to take into account that sure the bala is community but it is best kept with larger fish, and you have him in with tiny much smaller fish
not to make you wanna cry
just to keep you informed...
in fact.....
this might be a good reason for you to get another tank for you birthday!
just tell your parents if you don't get another tank your fish are doomed!

(exadurating of course!)
then turn on the water works and
TA DA!
