Hi friends, I have a bit of a conundrum. I have a tiger pistol shrimp and have paired it with a hi fin goby twice but I keep losing the gobies. The first one lasted about a month and the second one about 2 months. Both were happy and feeding after the first couple days then they disappear a few weeks later. The most recent one seems to have died and then been pushed out of the hole by the shrimp, no signs of being eaten. So I am wondering if this is common, am I just getting unlucky or am I doing something wrong! Other fish are a mandarin, a ruby longfin wrasse, tomini tang and some cuc. 60g cube.
