Yvonne Springer –
Added this goby to my 30-gallon reef tank after researching compatibility. It’s peaceful and has not shown aggression toward other fish or corals. Only observed minor nibbling on a small anemone, which I believe was accidental. Good choice for experienced aquarists.
Victoria Poole –
Felt like a good addition to my expert-level tank. It stays calm and doesn’t dominate the space. I keep an eye on it near soft corals, just in case. Size is within the expected range and looks natural in the setup.
Caroline Henderson –
It’s a bit shy at first, but settled in after a week. I’m cautious about placing it near delicate polyps. Overall, it’s a manageable species for experienced hobbyists with proper tank conditions.
