Lately I've been hearing mixed reviews about the conspecific compatibility of yellowhead jawfish. Some sites say that you can keep colonies in them in a sufficiently large tank and other sites say that they must be kept by themselves. Another site even says that you can keep 5-7 in a 55 gallon. I'm planning a 55 gallon jawfish tank with a 6 inch sandbed and 6 jawfish. Are there any flaws to my plan? And if anyone has any experience with this fish that would be great. Thanks!
