erm, i'm pretty positive that bala sharks are fully freshwater. (they also grow to be huge and need a 120g tank when adult.)

Both fish are freshwater fish. They will get along fine as long as you provide a minimum of a 75g tank and prefferably much larger.

Yes^^

But bala sharks need to be kept in larger groups (5-6) so a 125-150g would be better

How about 5 purple spotted gudgeons* and 5 or 6 silver dollars in a 75g? Or just 3 purple spotted gudgeons in a 30g with some smaller schooling fish (Giant danios, rainbows) ?

*Gudgeons are slightly different than gobies. Gobies have fused ventral fins that form a suction cup like fin that allows them to attach to surfaces (Candy striped gobies, bumblebee gobies for example). Gudgeons' ventral fins are separate, so they tend to swim more than gobies do, and rest on the bottom of the aquarium as opposed to the glass or steeply angled rocks. (Gudgeons include peacock gudgeons, the mogurnda genus, goo obo gudgeons, and sleeper gobies.)
This information could be wrong, but the difference in shape and characteristics between my candy striped gobies and any of our gudgeons seems to be significant. Our gudgeons swim, the candy striped gobies are usually (9/10 times) on the sand, rocks, or glass, they only swim to get their food

Oops, I went off track Oh well, I hope this info can help someone out

Gudgeon is just a regional name, here in England the Gudgeon is a small bottom dwelling Cyprinid (Gobio gobio) and i guess when people emmigrated they just named all the small bottom dwelling fish Gudgeons. The fish in question here are actually sleaper gobies ( Eleotridae )which as Dwarfs said are seperated from true gobies ( Gobiidae) by their split ventril fins

Well I was almost right
