Ingen’s Seahorse (Hippocampus ingens)
The Ingen’s Seahorse is one of the largest seahorse species. In the wild, they spend most of their time hunting for tiny crustaceans, using slow movements and camouflage to blend into their surroundings and avoid predators.
They display a range of colors including reddish to maroon, gray, yellow, gold, and various shades of brown, often with fine white vertical markings along their body.

The Ingen’s Seahorse is a striking addition to my 30-gallon tank. It has a beautiful maroon body with white vertical stripes. I feed it AlgaGen Tisbe daily and it eats readily. It’s calm and stays still most of the time, blending well with the decor. I keep it with one mate and they seem to bond well.

I bought this seahorse for my marine setup and it’s been thriving. The color is vibrant and it’s active during the day. I noticed it hides in coral crevices, which is typical. Feeding with AlgaGen works well. I’d recommend it for experienced aquarists.

The seahorse arrived healthy and has been very active since setup. It’s not aggressive and stays in one spot most of the time. The tank size is sufficient, and I’ve added 20 gallons for the pair. It looks natural and blends into the environment.
