Okay, that sounds encouraging, sir. If you have had the tiger tail for some time now, and it’s not losing weight, then it’s obviously getting nourishment one way or another.
It sounds like you have a sizable pod population in your tank, if you have a mandarin Dragonet and a pipefish that are thriving, so I suspect that the tiger tail has also been supplementing its diet by hunting Tigger pods and Gammarus amphipods. In fact, that could well be what all the hanging upside-down acrobatics have been about.
In short, Eric, if you don’t notice any other unusual symptoms, then I suspect all is well, and that your tiger tail is getting enough to eat, so keep on doing what you been doing, sir.
One other thing you might consider is to install a refugium on that day with spaghetti algae and then seeding the refuge with additional pods, feeder shrimp, and larval shrimp. The pods and feeder shrimp can reproduce in the refugium and some of them will eventually find their way into the main tank to help sustain your mandarin, pipefish, and tiger tail seahorse.
Let me know of who would like some pointers on how to set up such a refugium, and I would be happy to provide you with some additional information and guidelines.
Best wishes with all your fishes, Eric! Keep up the great work!
