This thread is old but I was thinking about pipefishes recently and came up with a few q's.
How often are you feeding?
What are you feeding?
Are you using supl to feed?
Also don't they prefer to live in pairs? you should get another lol.
basically all i did was pour LS (again from the oldest tank) into the media chanber of the AC, add some cheatomorph, and make fure the light gets to the algea... literally that it.
ser- i had a pair but the female (i think) died.. of all things from choking on a bubble..
i fed cyclopeeze about 1x a week and let them live off what was on the LR and from the fuge
to smith.. it's called google
no it's a type of macro algea people use in their sumps and fuges cause it grows super fast
