Would it be okay if I put 4 Bala sharks and 2 silver dollars in a 75 gallon tank?

  • We are currently upgrading MFK. thanks! -neo
Balas are definately to big to house correctly in a 75.
A shoaling fish that can grow to 15 inches,it's a no brainer.
Most silver dollar species are also unsuitable in my opinion. To be truly happy they need to be in large shoals in tanks over 6 foot. In small tanks in groups of less than 6, yours chances of skittish fish are high.
As already mentioned, lippincotianus is probably the best choice but I would get no less than 8.
Red bellies grow to around 12 inches live in shoals and are messy feeders.
You won't be able to keep many adults in that tank.
In my experience small numbers of natteri produces a boring display of skittish fish that hide a lot and hardly move.
Personally I would have a re think.

As far as Bala sharks looking aggressive,do you really think so?
Nothing but the made up shark name is remotely aggressive to me.

Have you looked at dwarf snakeheads?
Some won't grow much more than 6 inches,look aggressive and are true predators.
I'm actually now planning on getting 6 red belly piranhas in a 125 gallon (6 feet long) and instead gonna put 5 elephant noses and a rope fish in the 75 gallon
 
Hey I'm setting up a 75 gallon tank and I was wondering if it'd be okay to put 4 or 5 Bala sharks and 2 silver dollars in it. Would it be too small for them?

Thanks
This is an update: I'm gonna put 6 red belly piranhas in a 125 gallon and put 5 elephant noses and a rope fish in the 75. Does that sound good to you guys

I know nothing of P's, and have never kept ropes or groups of knifefish, but I would switch the numbers to 5 ropes and an elephantfish. Ropefish prefer groups, and elephantfish may show conspecific aggression if there aren't enough or the tank's decor is wrong.
 
Balas hardly get over 10 inches in captivity they would be fine a 75-90 isn't as small as people think and at least a group of 4 sliver dollars
I had a friend give me his 10 inch bala shark(in a 75) and he looked cramped just by himself. He was always jumpy and skittish.
Thats why you need a group of 4

There's several folks just on this forum alone that have balas well over 10". And even at 10", a 75 is too small for a decent group of 10" midswimming fish. I've had a 75. It is as small as I think it is. That's why I don't have it anymore lol

Yeah they don't get to 10" because they die young or are stunted due to too small of a tank. When given adequate conditions, a Bala Shark will reach 10".

I'm currently looking at my 75 right now, and I could not fathom putting a single full grown Bala in there, let alone the 3-4 needed to keep them happy. Especially after checking out a 10" Bala for sale at my local LFS yesterday. A 75 is not big at all, relative to what Bala's need and what people have on here.

Bala's are my favorite fish, and it sucks to see people like you spread information that is false that could harm the fish.
 
Camaro show keeps amazonian soft water fish and a smooth skinned fire eel in a 90 gallon. The tank is decorated full of dead sharp coral.
I can't think of a more unsuitable tank for its inhabitants.
The coral will buffer the water and could easily injure the eel.
He was also surprised to see his cichlids digging in the substrate. Asking if cichlids dig is like asking if bears crap in the woods.
Op,this is not a man who's advice on fish i would trust.
Camaro Show, If your not truly experienced on the subject it's best to stay quiet. What's the point in advising the wrong thing? It won't help the op,it won't help the fish and you can easily end up looking stupid.
