Awesome! What temp do you keep it at?
Seems to be holding at 69 degreesAwesome! What temp do you keep it at?
Thanks, another spot for me to spend money. LolI have a cold water reef. You should consider joining the Coldwater Marine Aquarium Owners group on FB. That's where I've found the most like-minded people.
Hey, I’ve been running a cold water local saltwater tank for two + yrs here on Long Island. It started when I collected a Black Seahorse, shrimp, crabs, conch, and other fish. This tank is by far the cheapest saltwater running tank ever! No heater, temp. range - 55 - 80 degrees. 2 basic freshwater filters. I do monthly 20 gal WC’s for a 60 gal tank. I collect the water from the bay, high tide.Thanks, another spot for me to spend money. Lol
Thats awesome I used to collect some shrimp and hermits from the sound but most of them ended up snacks to my fish so I don't anymore. I think the grass shrimp from the sound might actually be pretty good algae eaters. When I first got back into the hobby I caught a burrfish puffer from the sound but that was prior to my QT days and I lost most of the tank to brook. Apparently they come north in the current around the end of August. He was a cool fish, and never ate anything in my reef tank that he wasn't supposed to for the 6 months or so that I had him.Hey, I’ve been running a cold water local saltwater tank for two + yrs here on Long Island.

Collecting is fun, but be careful what you add. Single species fish is best. Fish grow fast. Collect mostly in the summer, but all extra bait fish and shrimp can be frozen for winter feedings. The only money I spend on this tank is to replace the filter pads, but only every 4-5 months, and then only one at a time.
Wow lots of good info in there. Thanks for the wrasse suggestion. My tank should stay in the 60's I'm not too interested in getting it colder than that.Katoi is the coolest water fairy wrasse. Good down to 68 or so. What temp range are you looking for? Most of us in the cold water marine aquarium owners group keep our tanks in the 55-60 degree range, but most of the temps being thrown around in here are more subtropical. If you're shooting for upper 60s, look into the wrought iron butterfly, Japanese pygmy angel, and conspicuous angel. There are some nice temperate gobies from Japan from the pterogobius genus, such as the white girdled goby. For blennys, I like the omobranchus anolius, omobranchus elegans, and salaria pavo. ORA breeds three temperate fish, white spotted filefish, kamohara bennies, and hulafish. Also, look into southern Australian boxfish like white barred boxfish and ornate boxfish. Potbelly seahorses, too. If going down to the true cold water range, look into yellowfin fringeheads and spiny lumpsuckers. Also, grunt sculpins although I can't seem to find a source. There are a few nice cold water anthias like cherry anthias and splendid sea perch. Best source for Aussie stuff is Steve McLeod on fb. For US stuff, Matsu collections. For Portuguese stuff, flying sharks
Depends what you call "cold water", ie Sea of Cortez, San Diego, Chesapeake Bay, Monterrey Bay, Washington State, Alaska? (restricting ourselves only to the US).
The temperatures in each of these areas vary greatly. Googling only (presumably surface) water temperatures in San Diego, the temp varies from 60-70 fahrenheit from winter to summer. (Water below the first thermocline, at wbout 30ft, is probably in the low 60s consistently). Monterrey will be notably colder at the surface, to say nothing about WA.
Far and away your hardest job with such a tank would be getting livestock. I know there are some species from the Sea of Cortez which regularly are sold (eg the blue spot jawfish, though there are others). That might be a good start.
ETA: i'd imagine the cost/trouble of cooling a tank much below room temperature would far outweigh the cost/trouble of heating it to tropical temperatures.
As an alternative, if you wanted to keep your tank at room temperature (low 70s), a tampa bay area tank or even a deep reef tank would work. Both could be run off of from Gulf Coast aquacultured rock. Corals could include non-photosynthetic sps and gorgonians (there are some very common and hardy photosynthetic SPS's that can grow up to the Georgia coast, or in deeper indo- Pacific Waters, but they're not very common in the ornamental aquarium trade). Ironically, many popular species of fish in this hobby - angelfish, flasher wrasses, hawkfish - come from deeper parts of the reef.
John Tullock's book "Natural Reef Aquariums" (available used) has a whole chapter on Tampa bay biotopes. Highly recommended.I'm just an hour North of Tampa and was considering a local biotope in a tank recently broken down.
Hey! I live in Washington state and had the idea of trying to set up a cold water tank for aggreate anemones, cant find much info about how to set it up ? Would it be the same bacteria as we use for regular salt tanks ? Also what is the temp for "cold water "
Love this thread! I have kept several coldwater tanks in my time. Here is my latest tank. For most coldwater tanks it’s about the invertebrates. There isn’t much coral. Cup corals, corynactis, gorgonians comprise most that you will see. And here is another tank I had. I had this one running for 3 years and is still my favorite tank ever. Tons of diversity.
Dude. That's amazing! Every aspect of this is golden
