Malanurus Wrasse attacking Court Jester Goby

[Boosterman]

I have a 75 gallon 4 foot long tank and 3'' Malanurus Wrasse is going after about 1.5'' Court Jester Goby every time. Goby is trying to hide into the rocks and is very timid. Is there anything I can try to reduce Wrasse's aggression or is this just how it is?

It’s not really even aggression, it’s more about his next meal. Had sim thing happen with a Melanarus and a YW goby. Next day saw goby’s tail sticking out of the MW mouth.

How long have both been in tank? What other fish? New tank where you could rearrange the rock?

About 2 weeks. First week showed no aggression but all of a sudden Wrasse is aggressive towards goby.
Yellow tang, Tomini Tang, Royal Gramma and 2 Clownfish are other tankmates. Rearranging rock is not possible since I custom made the rocks using Marco Rocks.

Man that’s not the news I was hoping for :(

Maybe that's where my Rainford's goby went... :eek:

Sorry, my YWG was pretty small though. Maybe feeding your MW really well may cause him to lose a taste for a Court Jester Goby snack. GL!

Could be. MW are hunters so when they see something small that is moving they go after it. Fish or not, it’s all fair game, literally. :)

Mine can be pretty hard on nassarius snails, so it's good that they mainly come out at night...

Sounds like one if them may have to go. The gramma and clowns are tough enough to hold their own. You're probably better off avoiding dartfish, small gobies and other small peaceful fish.

My MW was a jerk and rehomed him:)
