Fish to add to a nano cube?

fire fish, gobies, a pair of clowns? royalgrama

Live aquaria has a section for "nano" fish. Highly recommend starting there!

how big is your "Nano" ????

my nano's a 24G

I too would browse the nano section of liveaqauria.com. I had a shrimp/goby pair in my nano and loved to watch them Just be sure you choose a goby and a shrimp that pair up. It's pretty cool - the shrimp are basically blind so the goby keeps an eye out for predators, and the goby gets a home dug by the shrimp.

I have two nano tanks one has a pair of snowflake clowns, nalolo blenny, yellow clown goby and a pair of high fin gobies (barbershop) in my zoa tank I have a helfrichi firefish, swissguard basslet, tailspot blenny, blue stripe pipefish and a barnacle blenny. Just giving you ideas, you just need to study temperments and take into consideration tank size.

in my biocube 29 i had a jawfish, mandarin(not advisable), potters angel, clown, YWG, and a tailspot blenny. youd be fine with most any blenny. you could go with a smaller dwarf angel, possum wrasse, sixline wrasse, a flasher wrasse, clowns, firefish. there are tons of fish that can go in nano's.

From your other post I see that you have a firefish in there. What is everything currently in your tank and how long has it been running? This will help us advise you better
