Learned the Hard Way - Non Compatible Fish

I added some fish Tuesday....3 Green Chromis and a Pink Spot Shrimp Goby. The Chromis are doing great, the Shrimpgoby is fine, with the exception that he has an enemy.........the Lawnmower Blenny! I was not aware that a Lawnmower Blenny would have so much hate towards a Pink Spot Shrimpgoby! I guess they have similar shapes. That being said, the shrimpgoby stays on top of the rear powerhead and only comes down at feeding time. Personally I would rather give up the Lawnmower, but there is no way I'll catch him. So, I have a Pinkspot ShrimpGoby that I'll take an offer on or trade for another fish/coral.

Let me know ....Thanks

i just added a starry blenny to my tank and he has an enemy now too the black sailfin that is twice his size so needless to say my beautiful starry blenny is also hiding on top of the powerhead also

i bought a breeder box from petsmart a while back and used it to seperate my maroon clown from the other fish i left him in it for about a week and then i dropped him in after he was eating good and so on he swam around the other fish inspected him but didnt beat him up im gonna try it again with the starry blenny

Let me know if it works...

those two should be able to be in the same tank. the shrimp goby is a bottom dweller and the lawnmower is more of a "top of tank" fish. the reason that the goby is hanging at the top is because the blenny isnt letting him get comfortable in the tank. If you can, remove the blenny for a few days and let the goby get settled in. you should then be able to add the blenny back to the system with no problems.


Good Luck

All is well!! I caught the Pinkspot Goby(on top of one of the powerheads) in the fish net and placed him on the bottom of the tank. The Lawnmower wasn't too happy about it., he chased him for about 30 mins but after that it was over. Now the Goby has found a home under a rock on the bottom and Lawnmower isn;t harrasing him.
