I’ve looked online and it seems almost like a form to know how to aquascape or even how to align things in a way that looks pleasing to everyone. Any tips or pointers?
I’m not too sure that there is a good guide you can read that will help you. Most people try to follow the 2/3 ruling where you have 3/4 of the visual elements on one side, then a gap, and then another 1/4 on the last side.
Other times it really just comes down to what you think is visually pleasing (which is an opinion, so that’s why people find art either good or bad). I just would follow what you think looks good, or if you want to try to become better at it, watch some aquascape competitions and see how they set it up and what they did specifically. A lot of time it’s all about the flow where the fish aren’t there or are there just as a color aspect.
