Anybody Keeping a Temperate Tank?

[Van down by the river]

Hello Beverly,
I think asking someone from Vancouver Island to go collecting at low tide for you might give you some interesting critters. They can box it up, and send it. most of the tidal zone species are very tolerant of high temperatures.
This would be a suitable set-up for Catalina Gobies (Lythrypnus dallias) as well. The live rock will be fine, as many marine algae. You will probably have reduced growth rate due to the lower temp. Most inverts with the exception of corals and anemones should tolerate this temp, but a little experimenting will be necessary.
