No, not really. So long as there *should* be ample room and care given. The whale thing for example, I don't like if it hurts itself and is kept in a small place. But that applies to our fish too. If someone has a fully grown sailfin tang in a 10 gallon and somehow is hurting it, yeah I would feel bad for that tang. Conversely if the whale is well taken care for and seems to be doing pretty fine, even if it has to perform circus acts, then I am like 'eh whatever'.
