Sally Langdon –
The red starfish looks beautiful in my 55-gallon tank. It’s active and peaceful, and it doesn’t seem to bother other inhabitants. I’ve had it for three months and it’s grown slightly since arrival. Easy to maintain and a great addition to my reef setup.
Yvonne Manning –
I bought this for my first reef tank. It’s very colorful and stays calm. I didn’t expect it to be so adaptable to my water conditions. It’s now a regular sight on the sand bed.
Tim Wright –
The starfish arrived healthy and has been thriving in my tank for six weeks. It’s not aggressive and doesn’t interfere with corals. I’m very satisfied with the purchase.
