subtropical tank

[mollymonticello]

I hope I've come to the right place.

I'm setting up a subtropical system for seahorses (H. breviceps). The temperature will be between 65-69 degrees Fahrenheit. I can find and am planning to add a catalina goby, codium algae, and abalones...Do margarita snails need even cooler water to survive?

I've also found that some corallimorphs like "strawberry anemones" and a "hooded nudibranch" which actually eats brine shrimp could live in these temps. Now to find someone who has them.

It seems that most retailers and etailers don't sell cooler water species.

I'm looking for basically anything that could go in this system like macro algae, corals, sponges, inverts, etc. Don't have to be seahorse safe, there are two tanks and a sump/fuge in the system.

I'm also getting confused with words like "temperate" and "subtropical" and "coldwater." But I'm pretty sure mine would be considered "subtropical" and not "temperate."

Some tropical species could even do ok in those conditions, depends on the particular species. A good way to find out is to search fishbase.org for the distribution of the species. If it is found in those climes, it should be reasonable to assume you could keep them at those temperatures.

Caulerpa will definately thrive in those conditions. That is why certain varieties are banned in California.
