At 6:30 this morning, after my beach walk I checked out my tank with a flashlight as the light wasn't on yet. I saw all my fish fast asleep in caves and squashed behind rocks in the back.
Then I looked at the intake on my powerheads because if there was a dead fish, especially a pipefish, that's where they would be.
I didn't see anything there. I kept looking under the rocks and behind the UG filter tubes where dead fish find their way. No pipefish.
Then I spotted a yellow pipefish tail sticking out behind my long powerhead and assumed he was sucked into the back of the pump.
I shone the light on him, and he immediately smiled and lazily swam away. He is fine.
I couldn't find the other one, and it didn't seem that he was in the claws of a crab, so he is most likely fine.
I tried to feed them 3 times yesterday and didn't want to go overboard because my tank is approaching a jungle now with all the macro algae and hair algae in the back, where the fish rest at night, held up by the thick mat.
BTW, this is normal in the sea, natural, and the fish feel comfortable. Not so much in a spotless, no algae, no life tank.
In a few hours, when everything, including my wife, wakes up, I will try to feed them again.
I have a few different sizes and types of mysis and that's what my last one survived on for 7 years so I will again try that. I know they have not eaten in days, and if they don't start soon, it won't end well.
