I am considering moving my Mustang pair to a larger tank…They are in a 10 gallon that has invasive hair algae that I need to tackle. I have a 20 GALLON LONG set up in a better location with more light I think they would like…It is been waiting for other Seahorses that I plan to order at the end of the month.There should be enough room in a 20 GALLON LONG tank for 3 pair of Seahorses…I do not keep any other fish with them.
Is there any stress I should be concernend about? I don\’t think they have mated, just bonded. I\’ve always moved my goldfish collection around the house as I have wanted without any problems.

Transferring your Ocean Rider seahorses to better quarters should not present any problems. Preadjust the water in the 20 gallon aquarium to the same temperature, pH, and specific gravity or salinity as their present tank, and you won’t even need to acclimate them.
Of course, being handled, uprooted abruptly, and transferred to strange new surroundings is always somewhat stressful for seahorses. But in your case, no shipping stress whatsoever will be involved, and your pair of seahorses will be transferred together, which will make much less dramatic, so things should go quite smoothly and they should adjust to their new environment quite quickly. Make sure your 20-gallon setup has plenty of hitching posts and lots of shelter and sight barriers to give the seahorses a sense of privacy, and I can foresee no difficulties with the upcoming move. In time, your seahorses should really appreciate the move into more spacious quarters that are twice as big as their old tank. That’s a nice upgrade you’re planning and I heartily approve!
My recommended stocking density for H. erectus is 1 pair per 10 gallons (~40 liters), so a total of two pairs or four individuals is about right for your new setup.
I’m sorry to hear about the hair algae that’s proliferating in your 10 gallon aquarium. It can indeed be very tenacious and difficult to eradicate once it gets out of control. Sea hares will chow down on green hair algae, so a Sea Bunny may help you eliminate the hair algae, but then you’ll have to supplement its diet once the algae is gone.
The main thing when combating hair algae is to cut down on the excess nutrients in your tank. If you have to, use Phosphate Reducer to remove excess phosphates and a Poly-Filter Pad (from Poly-Bio-Marine Inc.) to remove excess nitrates. For more details, check out the suggestions from the following thread from an earlier thread titled "Hair Algae," which you can find at the following URL:
If your tap water quality leaves something to be desired, then consider buying reverse osmosis/deinonized water (RO/DI) for topping off and water changes instead. Most well-stocked pet shops that handle marine fish sell RO/DI water as a service for their customers for between 25 and 50 cents a gallon. For example, WalMart sell RO/DI water by the gallon for around 60 cents. Even my drug store sells RO water nowadays.
Natural seawater is another good option for water changes. Like RO/DI water, natural seawater can be purchased at fish stores for around $1.00 a gallon, depending on where you live. It sounds expensive, but when you consider the alternative — paying for artificial salt mix and RO/DI water and mixing your own saltwater — then natural seawater is not a bad bargain at all. It has unsurpassed water quality and seahorses thrive in it.
Just remember that Reverse Osmosis (RO) or Deionized (DI) or RO/DI is very soft and must be buffered before it’s used so it won’t drop the pH in your aquarium when it’s added.
Here are some online articles with tips and suggestions for controlling outbreaks of such nuisance algae:

Check out the articles, use phosphate reducer to eliminate excess phosphate and a Poly-Filter Pad to remove excess nitrates, and use only phosphate-free, low ash activated carbon.
If you can get a seat here, then bolster your cleanup crew with additional snails and/or micro-hermit crabs that eat slime algae and other types of nuisance algae. Astrea snails, red foot moon snails, and Scarlet reef hermit crabs (Paguristes cadenati) all fit the bill and would be good additions in that regard.
Introduced as soon as possible to a new aquarium, as soon as the ammonia and nitrite levels are safe, Astrea snails effectively limit the development of all microalgae. In other words, they are good at eating diatoms, but will consume red slime and green algae as well. The Scarlet Reef Hermit Crab (Paguristes cadenati) is a colorful micro-hermit that’s a harmless herbivore. So cannibalism isn’t a concern at all for these fellows, nor are they likely to develop a taste for escargot. As hermits go, most of the time the Scarlet Reefs are perfect little gentleman and attractive to boot. I even use them in my dwarf seahorse tanks. Best of all, they eat all kinds of algae, including nuisance algae such as red, green and brown slimes, as well as green hair algae.
Best of luck eradicating your nuisance algae program, Harry!

My only concern is that the 20 gallon long tank is not that tall (~12 inches) which could impede breeding especially in full grown erectus.
Best of luck.

That’s an excellent point Kelly makes about the height, and therefore the water depth, in a seahorse tank. Your 20-gallon aquarium is a very nice upgrade for your seahorses since it is twice as spacious and will provide double the water volume for increased stability, and the move should go smoothly without being too stressful for the seahorses at all, but a 20-gallon Long aquarium is lacking in the height that is so desirable for a seahorse setup.
As Kelly pointed out, the height of the tank is important because seahorses need vertical swimming space to perform their complex mating ritual and successfully complete the egg transfer, which is accomplished while the pair is rising through the water column or drifting slowly downwards from the apex of their rise. If the aquarium is too shallow, eggs will be spilled during the transfer from the female to the male’s brood pouch, and mating becomes increasingly difficult or impossible below a certain minimum depth. A tank that’s only 12 inches tall can be problematic in that regard for large seahorses such as Mustangs and Sunbursts (Hippocampus erectus).
More importantly, a tall aquarium can also help protect the seahorses from depth-related health problems such as bloated pouch and certain forms of Gas Bubble Syndrome (GBS). This condition is caused by the formation of gas emboli within the blood and tissues of the seahorse, and in all its various forms, GBS is the most common health problem seen in seahorses that are kept in small closed-system aquaria. If untreated, the gas bubbles worsen and the condition is fatal.
Tall aquariums are preferable for our amazing aquatic equines because the greater hydrostatic pressure at increased depth is known to protect seahorses against GBS, whereas the reduced hydrostatic pressure in shallow aquaria is known to be conducive to GBS. For this reason, it is always desirable to select an aquarium at least 20 inches tall (the taller the better) for a seahorse setup.
So while your seahorses will certainly fare better in your 20-gallon aquarium, Harry, and I certainly encourage you to make the move and upgrade them into a bigger tank, it would be even better if the new tank was a 20 gallon Extra-High All-Glass Aquarium (20"L x 10“W x 24“H) rather than a 20-gallon Long aquarium.
Best of luck upgrading your seahorse tank and relocating your seahorses, Harry!

Kelly & Pete:
Thank you both for your suggestion on the HIGH Level tank for my Mustangs. I will definitely look into that purchase right away!
The tranfer was accomplished, and went very well. They are loving the new space and the lighting that is better in the larger tank location. There is more natural light.
Winter in Georgia is mild but still cold enough to bring indoors from the pond some of my more temperate goldfish beauties. I can always use the 20 gallon long for them!
