Hi there,
this is my first post here and I'm from the UK so I hope you dont mind me registering. This just seemed like a very, very good sw board !
I keep what looks to me to a very similar species of mussel here but in coldwater/temperate conditions. Some I've got from the beach, some from the local supermarket (to use as pufferfish food). This batch seems ok so far (4mths) but the water temperature has been way below tropical reef temps - 60F max. I've tried collecting and keeping them in the summer and lost them due to either high temp or inadiquate filtration.
These are in a tiny hex 20l coldwater native marine tank in an outhouse with an overhead trickle filter and with very few inhabitants - just several Actinia equina anemone's. No fish. I'm hoping that the mussels get enough sustanance from the frozen food I feed to the 'nems.
I've also tried tropical oysters in m my 150l reef, these lasted six months for no obvious reason apart from feeding. These has access to coral food but I wonder if it was enough. If they were Mediterranian sp then there may have been heat stress too.
have had some trop mussels growing on my LR for years - they seem to do OK but are tiny.
The point on possibly introducing a possibly invasive species is a valid one - the zebra mussel is a case in point.
Interesting thread...
