Seahorse tanks don’t require just glass and food. These creatures has their own set of needs. Before you purchase anything, know the seahorse(s) you want to keep. They are not like other fish so if you treat them that way, you will fail.
The chart indicates the difference in each species’ tolerance for temperature. While some species tolerate warmer temperatures, others prefers it cooler. Don’t mix ’em up. For example, a warm-water seahorse stressed out in a cool tank won’t live long. Likewise, a cold-water one won’t thrive in a heated tank. Match what you have (the livig situation) based off what you want to keep (the animal).
How to Set Up a Seahorse Tank
Looks shouldn’t be the only standards. Space is also important. I believe many folks greatly undervalue how high a tank should of be. Because seahorses are an inefficient swimming animal, they gets tired quickly. Additionally, they don’t have a true stomach. That means they’re always eating. They need places to relax. Plus, one parent carries the offspring (the male).
Vertical space is required. He must has enough water depth to perform his birth lunge without touching top of the water. In other words, if you want them to breed, make sure your tank isn’t too short. How do you know how much? Simply multiply adult size by 3. This will keep things from getting ugly when breeding time comes around.
Captive bred seahorses can be fed frozen foods whereas wild caught ones will not readily accept prepared food. Their programming tell them to pursue live movement. They become used to eating only live mysis shrimp, which can go missing. Captive bred seahorses is accustomed to eating frozen food so you aren’t playing a high-stakes game of convincing them to survive every single night. The best practice for seahorse keeping is switching to captive bred. Not only does it save you money but it eliminates some of the hidden parasites (which frequently kill wild seahorses during the first month).
Reducing stress are also good. Because of the water’s importance, this hobby differs from many other saltwater hobbies. Whereas other saltwater species can tolerates some degree of impure water, seahorses cannot stand any ammonia/nitrite whatsoever. Contaminants immediately gets absorbed into their gills. There’s no time to wait for a new tank to “cycle.” From day 1, the water has to be pristine. You need strong filtration. Maintenance should be strict. Water parameters should be tested weekly. Why? This will help you detect problems early enough to act before it’s too late.
Also critical is salinity stability. Osmotic stress caused by fluctuating salinity weaken the immune system. That makes them vulnerable to bacterial infections such as snout rot. Watching them is important to your success. Are they on their hitching post? Do they look like they are anchored well? Or do they look like they have become exhausted and need to stop and rest? How are they feeding? Do they have a sunken abdomen telling you they’re hungry?
The beauty of this hobby is it’s not one full of flashy behavior. But it is rewardinger to know you have an established ecosystem. Knowing when a male drops his fry into the tank is rewarding. It tells you you gave them what they needed. And that keeps people hooked on these gentle swimmers.
