Please do share a video or soI have a group of 6. Got them at 5cm. Now, 1.5 years later, they are around 35cm and still together.
They do fine, although they do ***** a bit at eachother. I have many plants, which gives them all sort of their one space when needed.
An honest addition: im not sure if it will continue to go well in the future. As the *****ing only started recently, im not sure how it will evolve. But thus far, not a single problem.
This looks very promising
BTW how big is your tank
