Man I am stuck in a weird situation, my lionfish is sharing same hiding place with velvet demsel from 3 days now and I am afraid that it may sting it. At starting, I thought that lionfish is attacking it but now I am sure it is not attacking. I am just confused as it is the first time I hv seen it . I hv attached a vedio. It is hard to see demsel but if u look closely, u may find it hiding with lionfish
