Mantis tank change

[spoons]

Hii I wanted to come to the experts and ask do you think my mantis would be bothered if I change his tank size to a 55 to a 15

sorry the 55 looks a lil dirty I’m fixing an alege problem

if the base dimensions are similar i imagine it would be fine. i personally wouldnt go much smaller than what the base of that 55 looks to be
