Is This Nomal Behaviour For A Cory

[TigerOscar11]

I am well aware that he should NOT be on his own and i plan on getting him a mate or two very soon, but im not sure if this is why he is acting like this or wether it is normal.
In the video he normally acts a lot more erratic.

cories do need to be in a group of 6 or more, but I would say the behavior is normal Albinos are a very active cory, and any cory really will tend to do this in a new tank.

No. Your flow is a bit too high for cories. They live in sluggish streams btw. Your stocking is also quite wrong. Id say remove the shark.

That flow is all I have, the shark was given to me by a family member as she couldn't have it anymore. And he is going to be rehomed eventually

Its very normal behavior for an albino cory, although as stated above, you flow seems too high.
I would suggest you get another 5 though.  Better in groups of 6+.
 
Also, I notice that you have gravel in the tank.  Not the best sub-strait for corys.  Look at getting sand if you can.

Is there a way i can lower the flow, there isnt anything on the filter and atm i cant afford a smaller filter
I have another filter, but that is on my 60ltr and only rated for a 75ltr tank.....
 
I would like to get some sand for him, i was worried about that. I have a bristlenose in there as well, wouldnt 6+ cory's be overwhelming?

I'd honestly think about returning her to the LFS or rehoming her. The conditions are all wrong, from the gravel to the small size of the tank to being alone to the high flow rate. 

 

[TigerOscar11]

I am getting a bigger tank soon so i can probably put her in mums tank for now she has 3 corys in hers

 

[This Old Spouse]

That sounds like a good idea. What kind of substrate is in hers?

 

[TigerOscar11]

Mostly gravel atm, but i will put some sand in there

 

[This Old Spouse]

That really doesn't work too well. The sand ends up sifting all the way to the bottom.

Ill take some rocks out of an area

Agree, tank too small. No sharks. Sand not gravel.
As to flow, well I have stronger flow, and mine spend a good deal of time playing in the flow along the front of the tank. But I also have plenty of areas with lower flow. Good for the kids to rest, but also require vacuuming more often.

My tanks have always had a higher flow too. My larger cories never had any issues, and the smaller ones always found the areas without the flow to surface. You could try adding a sponge to the top of the filter where the water comes out, that will slow it down a bit.

I personally, would worry more about the size of your tank.

So rehoming my shark for now would be best option?

The flow is mostly on the left as the filter faces the front of the tank, so there is low flow on the far right of the tank, i have seen him resurface last night so he is alright, i am thinking of redoing substrate as 50/50 gravel and sand on either side of the tank as my pleco likes the gravel

EDIT: i have a BN pleco, nothing huge

My mum has a 300ltr tank so could i put the shark in there for now?
How big will he get and roughly how long before he is an issue?
I am hopefully getting a new 400ltr tank soonish, like within a few months
