Who Gives A Fish Forums

Alright i'm looking at fish again.....

Current fish in a 20 gallon long reef are a Pecula Clown, Firtideflow, zenixzenix Zen Archon

sixline wrasse is a good choice, bangai cardinal fish too.

Not a fan of cardinal fish, to be honest. I've been reading up and I'm not sure a sixline wrasse would be the best fit for a 20 gallon tank. I might still consider it, though. Need to do more research.

Suggestions welcome - I'm clearly indecisive here.

Longnose Hawkfish, pretty cool fish.

Not suitable for reefs, and it can grow up to 6".

Actually, longnose hawkfish are fine in a reef setting, they're considered reef safe. The issue is they do get too big for a 20 gallon.

What about a piped filefish? They're pretty interesting, just gotta make sure you're feeding them enough.

the thing with pipiteflow is they seem kinda fragile, especially when they're resting - i can picture them getting pulled into a powerhead.

I've been reading that they can be reef compatible, but there's a risk of them nipping at corals. Don't wanna take that chance, which is why I said they aren't reef safe for my setup.

Considering a small flasher wrasse, maybe something like a carpenter's, could work out. Blennies or gobies are also an option, like a neon goby - they're pretty interesting.

I was gonna throw out a crazy suggestion like a Great White Shark, but that's obviously not gonna work in a 20-gallon tank. For something a bit more realistic, what about a Damsel fish or a Chromis? Both are pretty peaceful and should stay small enough for your tank. A Royal Gramma Basslet could also work, or maybe a small Wrasse like a Carpenter's or a fairy.
