There was a lot of discussion about the possibility of sea otters arriving in a previous thread. After a delay, a couple of seals were moved into the newly completed exhibit temporarily; but he sea otters finally arrived and went on show just before lockdown in March 2020. @Brum and @cliffxdavis reported on them briefly, and I made a mental note to visit them in the summer when they had completely settled in - indeed I had suggested to @bongorob that we might go together to see them. However circumstances changed 
When I was planning my short zoo tour in October, I had to include a visit Birmingham to see and photograph this new species, particularly as thee were no photos in our Gallery. I have posted some photos of the exhibit and the otters, which I will describe a little more here.
I had not visited this Sea Life Centre since 2005, so there were some new features including the gentoo penguins in the first exhibit after the entrance desk. But the first view of the otters comes after walking up the ramp beside the entrance atrium, past the shallow tank which holds jacks, guitarfish and other medium-sized marines: looking up through a tall window opposite the clownfish tank (Nemo! Nemo!). This window shows the bottom of the otter's pool. I could see the two otters playing at the surface with what appeared to be a green plastic dustbin lid. However this deep area acts as a sump and the bottom of the pool was covered with assorted rubbish. I don't know if there is a bottom drain, but if there is, it obviously hadn't been used for a while before my visit - when one of the otters dived to the bottom, I tried to take a photo, but so much muck was stirred up from the bottom that my camera wouldn't focus
There is small window viewing the surface of the pool at the top of the final ramp, but the main display is on the top floor, just beyond the lady with the camera gear who offers to take photos of the visitors. There are plenty of signs about the otters ('Ozzy' and 'Ola') and a screen showing some YouTube videos. The view from the main window is shown below.
The green area is the deep section of the pool, and the small door in the back wall leads to the off-show area. When I arrived it was open and I could just see an otter inside.
Walking around to the left to the second window revealed slightly more of this area and I could see the otters diving and playing in a small pool off-show.
After I had waited for a while, one of the keepers opened a hatch and threw some food into the main pool, so the otters rushed out and the door was closed - I guess that the off-show area needed cleaning.
As the otters are now between 2 and 3 years old, they are still immature and I was surprised how active and playful they were. The pool contains several toys for them. The female was having great fun with the green 'giant frisbee' (as a sign describes it) - she dragged it into the pool, both of them played with it there, then she dragged it out again and sat on it.
I do share the concern expressed in the previous thread that the enclosure is not particularly large, but the pool is deeper than I expected and the presence of the off-show area is another good feature, which the otters obviously like. I have mixed feelings about the fact that there is no open air section: it might have been possible to construct one, if I recall correctly, the small-clawed otters did have one, but sea otters are known to be sensitive to disturbance, so perhaps this option was ruled out.
Note for photographers. The lighting of the exhibit is horrible - there are coloured spotlights, but the overall lighting is dim. So high ISO settings and large apertures are required, particularly as the otters are so active. This means that my images are very contrasty and many of them are blurred because of motion or missed focus, and virtually all of the otter shots needed colour correction to remove colour casts or coloured highlights from reflections of the lamps. This partly explains why it has taken me so long to post these photos. But I do want to have another go - I like a challenge and I haven't forgotten my offer to @bongorob
