Do rounded or half-moon fish tanks harm my fish or distort vision?

Updated On September 23rd, 2025

Hi! I was wondering if rounded fish tanks were harmful to the fish. I have seen that fish bowls are harmful but was wondering if a half moon tank distorts their vision or causes any other problems to the fish.

It should be okay to use these tanks as long as they have proper filtration, lighting...etc. Round bowls typically don't have filtration, lighting...etc and that's what will adversely affect the water quality. I hope this helps.
