Experience with Yellow Cardinalfish (Ostorhinchus luteus)

[Jaroen]

Hello everyone, I'm new to the hobby and new to the group.

And I'm looking for some (expert?) help.
My plan is to have a small group of Yellow Cardinalfish (about 9) in a 300 liter (75+ g.) mixed reef aquarium.
It is my starter saltwater aquarium with mostly mushroom and leather corals.

For stocking fish and invertebrates I'm using https://www.reeflex.net/ (Meerwasser Lexikon) and https://reefapp.net/en/ (Reefapp Encyclopedia) to have some information on the basic data. This helps a lot! But . . . real life experience is so important.

Can anyone help me and share their own experiences?
I'm thinking about those little surprises no-one expects. Things with feeding, behaviour, aggression, breeding and such.
Because reading that websites it looks like Yellow Cardinalfish are troublefree fish. Right? But . . . ???

I'm planning to stock further with other hardy and peaceful fish like a pair of Purple Firefish (Nemateleotris decora), a Segmented sailfin Blenny (Salarias segmentatus) and a Gorgeous prawn-goby (Amblyeleotris wheeleri). And possibly a few other fish added (Forktail blenny and/or Banggai cardinals). Aside from snails and a few shrimps.

I'm hoping the group of Yellow Cardinalfish will offer an interesting stocking. But, how are Yellow Cardinalfish in practice???

Thank you!

I've also wondered about these small yellow cardinalfish. Does anyone have some information to share?

Biota or ORA have had them listed for sale . I don’t know how often they are in production . But those would be a great source to start with .

We have a group of 4 in our office tank and they're a pretty worry free fish. They compete well for food with tang, angels, blennies, and other species. They aren't super aggressive except when they have eggs but even then not much

I'm sure this is a question that annoys you guys but are they something that is in production often? I would love a group.

I got lucky , I had a lfs bring some yellow lined cardinals . Got a pair but yet have not seen one carry eggs . Still waiting . Although I tried a group of 4 in a 125 . They paired up and definitely will not school together in a larger group . Of the two pairs 1/2 of a pair developed an eye embolism and perished . Still keep the other one in case I loose one of the other pair . Still can’t tell who is male or female . They do like to hide in the coral rock recesses making it difficult to catch them
