Who Gives A Fish Forums

I've got a 35 litre setup with plenty of live rock, and I've currently got a few inhabitants - 2 peppermint shrimp, a cuc, and a tailspot blenny. Considering adding a Rainford's goby, do you think that would be okay with the blenny, or would it cause any issues?

It's probably fine to add a Rainford's Goby, but keep in mind they can be quite delicate. Just a heads up, make sure the fish is eating well at the store, or your tank has plenty of food sources like filamentous algae and pods for it to thrive.

I'm wondering, would green hair algae be considered a suitable food source for the Rainsford's Goby, falling under the category of filamentous algae?

Yeah

Definitely getting a Rainford's Goby now.

Honestly, I'm not sure a Rainsford's Goby would thrive in a 35-litre tank, just my opinion.

I'm finding this quite perplexing, as the Rainsford Goby is often cited as suitable for very small tanks, which seems to contradict the concerns about my tank size.

Yeah, it should work out alright

I'm not convinced the tank size is an issue for the Rainsford, actually one of the few fish recommended for small tanks, so I'm a bit puzzled by the size concern.

Rainsford's gobies are notorious for overgrazing in smaller tanks, similar to mandarins. They're notoriously finicky eaters, making the transition to dead foods a real challenge.
