Marino:
I dont mean to sound "holier than thou", but you did collect fish which you do not know the species. I am very impressed that you did some research, most people would not have taken this step, so you obviously do have a strong interest in ecology and conservation. However, the statements you made are nonetheless concerning, because you did collect these fish not knowing what they were (aside from knowing they are blennies). The fact that these fish appear plentiful is not a good speculation- this is exactly what hunters of passenger pigeons assumed, and we know what happeneed to them.
At any rate, you did take steps which I admit were ethical and logical, so perhaps my previous post was a bit aggressive. I just fear the action of collecting fish and containing them in aquariums without research as to their care and husbandry can be problematic and generally discouraged. But then again, I would hope anyone using this forum would also have the ability and presenece to avoid this scenario.
