Atlantic Tarpon Growth Rate? Also show me your Atlantic Tarpon!

  • We are currently upgrading MFK. thanks! -neo
Start off in 37, then 55, then if I can get a 100+ gallon stock tank and then after that or if I can’t get the stock tank it’ll go to a local public aquarium.

If you're looking into Atlantic tarpon, here's some idea on their growth and tank needs:

In the Wild:Tarpon grow pretty quickly. In their first year, they can hit around 1 meter (3.3 feet). By the time they're about 10 years old, they’re usually around 2.5 to 3 meters (8 to 10 feet) long. Of course, their growth can vary based on food and environmental factors.

In Captivity: When kept in an aquarium, their growth rate can be a bit different, depending on how well their tank is maintained. With the right conditions, they can still grow quite well, but you might see some variation based on how you manage their environment.

Tank Size: For an adult tarpon, you'll need a massive setup. Ideally, the tank should be at least 4 to 6 meters (13 to 20 feet) long, and make sure it's wide and tall enough to let them swim comfortably. Good filtration is a must because these guys are pretty active and produce a lot of waste.

Hope this helps with your planning!

Just multiply each of those by 6, and then you'd be looking at a grow-out tank for a very small Tarpon. Still, even if you are raising it for a public aquarium, it isn't a good idea to raise it at a home aquarium unless you have something like the Ohio Fish Rescue's setup in your backyard. (If you don't know who I'm referring to, check out their Youtube Channel; it's called Ohio Fish Rescue).

I know you OFR is. Big fan. Also tons of people grow out giant fish for fun and I’m no different so I’ll still grow out what I want.

Just because other people do it doesn't mean it's a good idea. Trust me, I had the same mindset. I wanted to grow out a Silver Arowana (hence my username), large catfish, large cichlids, and pretty much anything that couldn't fit into my tank for the thrill and fun of it. But these kind folks talked me out of it, and I'm grateful they did, as I now have fish that properly fit into my tank, and I have no stress worrying about size and when I'll have to get rid of them. It makes your fishkeeping experience so much better when you don't have to worry whether your fish will outgrow your tank. Get fish that fit your tanks, and you'll be much happier.

Until you have the space to properly keep your dream fish, whatever that may be, find smaller fish that look like the fish you love. For example, instead of stuffing a 4 ft+ long Silver Arowana into a 55 gallon, perhaps consider an African Butterflyfish, which has the same profile, a fraction of the size (4-5 inches compared to 4-5 ft), and just overall better for that tank size. That's just one example; there are many, many more examples; finding those smaller alternatives might change your mind on the larger beasts and lead you to options you didn't even know existed that are usually cooler than the big boys, not to mention usually much more manageable and cheaper to keep overall.

I hope this presents a different perspective. Best of luck on your fishkeeping journey! :)

If you can help me find a species that won’t out grow a 55 gallon that looks like an Atlantic or even an Indo Tarpon I’ll consider.

There are quite a few tetra species that come to mind that look like mini tarpons, but if you would rather something a bit larger, a pictus catfish could work (I know they have long whiskers, but because of their mostly silver and sleek profile, they look like Tarpons sort of).

I'll keep looking and see if I can find something better.
 
Ah, I found one that I think will tickle your fancy...Dwarf Vampire Tetras. They look like a cross between a Payara and a Tarpon and are manageable in size. Only Lone Star Exotics has these guys (I've seen these in person at a show where Lone Star Exotics were; they were really cool). Their care might be a little bit advanced, so that is a downside, but here is a link to them: https://www.lonestarrareexoticfish....-tetra-roeboides-affinis-for-sale-online-live

I want a fish that really looks like a Tarpon. Pictus look nothing like a Tarpon
