My Bala/Silver Shark is swimming up against the edge of my tank going up and down, not looking to happy.

I have seen them do this before many times. They usually stop after a while and return to normal swimming patterns. The only cause I have ever been able to identify is over crowding or a tank that's a bit small for them.

Bala/Silver sharks are large, fast-swimming shoaling fish that should be kept in groups of 6 or more. For juveniles, the minimum tank size is 4ft, but by the time they're adults, their speed and size demand a realistic tank size of 7-8ftft to deal with the swimming room. And you're right to be worried about the guppies and tetras. Once they get big enough, the sharks will more than likely predate on anything small enough to fit into their mouths.

Sounds like stress. Silver Sharks get extremly large growing up to 12" in length they also like company of another silver shark, or a group of!
They require a tank of at least 3ft preferably much large with lots of open swimming areas. if they cant do what comes natural to them they get stressed. If they remain stresses for long periods of time then they may become more open to infections and viruses.

Doesn't sound good... I would get your water tested. It may just be a chemical imbalance. However, don't change your water because you have to let your nitrogen levels and all that develop in a tank. ( My husband and I made the mistake of simply trying to change the tank water and ended up doing more harm than good.) However, there are a lot of great chemicals and other things at stores like Petsmart that you can get to regulate all of that, and hopefully help your fish out.

It could be that your shark isn't happy with water conditions. Check your ammonia, nitrite and nitrate levels. If any of those are high then do a 25% water change.

Unless he is looking very pale, and not eating it's ok. Mine used to do that. He will get fed up of doing that and go back normal.
Check your water just to be sure. Make sure there is not too many fish in there either. :)

try asking a vet who is trained in dealing with these sharks

Did you just get him? If you did, then he's probably adjusting to his new home. If you got him a long time ago, then it's probably bored. Add some more decorations so he can hide and play in it.
