Unfortunately someone left my son's lid ajar, and his Randall's gobie jumped. He wants the same gobie, but I'm having trouble finding one online that doesn't already come with a paired shrimp. If I got one with a shrimp would the teo shrimp get along? This is for a 15 gallon cube. The new shrimp would be separated from the fish for 76 days to quarantine him if that matters to this senario.
