So this morn my fiance text me to tell me thats the jade goby we bought for her father about 7 months ago had died. She said he fed the fish and he ate and was fine and this morn he found him dead. This fish liked to move rocks all over the tank so I'm thinking he may have choked on rocks. This fish was in freshwater although ppl say they need brackish but this fish was thriving. I bought him for her father at about 4 1/2 inches and at the time of death he was all of 9 or 10 inches and a big fat boy. He ate out of ur hand and loved when you walked up to the tank. My plan is to buy him something this weekend and he doesnt want another goby cuz he like his too much and doesnt wanna replace it with another. He has a 55 gallon with a parrot fish and a african knife fish. I wanna get him something with personality and that can live in the 55 for life. Any ideas would be great.
