I see him going up and down and to the sides very fast right?

Sadly I won’t be able to go back to my house until the weekend. And today I saw one of the panda Cory’s is gone. Not sure why it died but the shrink crew cleaned up and did not find a body.

I was thinking of adding 2 more panda Cory.

I had 3 punctatus and 3 panda. Now it’s 3 punct, 2 panda.

They seems ti be eating just fine earlier when I went. But now seeing the live feed. I don’t see the others (hiding maybe) and this one panda swimming fast.

Did the water change on Saturday , did not see one was missing.

Parameters were

0 amonia
0 nitrite
20ish nitrate.

So I did a 30% water change to not let that go to 40.

20 gallon tank.

2 honey gourami
8 dwarf rasboras
4 Otto catfish
6 Corydoras
30+ shrimp.

Hey everyone, looking for some advice from people who keep dwarf rasboras or are familiar with this filter.
I have a standard 20-gallon tank (the regular/high footprint, not the 20 long). For filtration, I’m running a Sicce Aqua Filtra 20.
Right now, I have the filter running at its maximum setting. However, I keep my tank water level filled up above the outfall, so there is no waterfall effect, crashing, or surface splashing—just a steady stream flow.
Here is my current stocking list for context:
8 Dwarf Rasboras (just added them two days ago)
3 Panda Corydoras
3 Corydoras punctatus
4 Otocinclus (Otto) catfish
Around 25 shrimp

The rest of the fish have been there for months now.

Given how tiny dwarf rasboras are and that they generally prefer calmer water, do you think this setup creates too much high-velocity flow for them in a standard 20G? They have to swim against it quite a bit if they cross the middle/upper column.
The bottom dwellers (corys, otos, and shrimp) seem totally fine since the flow is mostly at the top, but I'm worried about the rasboras. Should I dial the Sicce down a bit, or is keeping the water level high enough to buffer the blast sufficient?

I am not an expert so idk if having the flow at lower than the max could result in bad filtration.

Thanks!
