There is no reason every life can't be equally valued, while the possesion, in the vague sense of the word, does cost money.
Would you be more upset about breaking a $200 vase or a $5 vase?
There can be two different levels of loss here and they don't have to be mutually exclusive. One may regret the loss of life for a chromis substantially less simply because they are not regreting the minimal monetary loss compounded to the first as they would to the loss of a lineatus wrasse.
The problem is not whether one should respect a life form in one's possession more than another as long as suitable care is given to both.
