I have a hector's goby for about 2 weeks, and it was doing fine...and yesterday i add in a six line wrasse, rainford goby and a scooter blenny... And I think my six line wrasse is the one who injure my hector's goby...I just came home and on the lights and take a look at my tank, and after about 5 mins or so, I saw my hector's goby being carried by the flow around my tank and it is desperately trying to swim and balance itself...it's still ALIVE!!! so I quickly net it out and put it in my quarantine tank that is always there when something happened...Now the hector's goby is in my 3 gallon quarantine with only one piece of live rock that cover's about 3/5 of my 3 gallon QT...I am hoping that the hector's goby have chance of recovering...cos I dun see any torn fin or watsoever...I only saw some red patch in the internal near the head, around the gills area...I was wondering if it will recover, and if it does what should I feed it? I do not have any sand in the QT... Will they feed on live plankton? If I pour a little bit into the QT, will it help???
