Depressing!!

My new little foxface suffered the same demise as my old one. It was hung on the return of my closed loop when I woke up this morning. Not sure why this is happening. I have 8 other fish in the tank of various sizes that this has never happened to and the other foxface had been in there for 3+ years. Now its happened twice in just a matter of a couple of weeks. I did lose an RBTA the same way once. Anyway, I gotta get something figured out to try to keep this from happening again. I've got the return split 2 ways already to reduce the pull on it and if you put your hand on it there doesn't seem to be that much pull, but guess its different for the animals in the tank.

He was more than likely dead or dying and got pulled or drifted to it.

Some fish would be more prone to being trapped against the suction side of a closed loop due to their body shape and habits. Rabbit fish pose a double whammy because they have thin tall body so if they were to get against the intake they could cover a lot of the openings with their body and consequently increase the suction force being applied. Another problem is their propensity to hide and the pipe work the way it is arranged may offer a tempting place to retreat when startled. Fish size and strength as well as suction force all play a part. You also need to pay attention to the intake to make sure that as things grow on it it is not becoming restricted which would increase suction force.

looks like some gutter guard will help if it can be put over your return.
sorry to hear about the loss

Eeeewwww!!!! It was "hung on the Return” (?!) side of the pump??? The pressurized side TO the tank?? Or do you mean the suction side, like Dave said? Ryan, I’m having a difficult visualizing your set-up.

Here’s the bottom of my tank, with the closed loop drain and manifolds shown:

And here is the (painted) Closed Loop Drain Stack and "return" lines. It might be hard to see, but there are Three (3) open sides on the Standpipe and with this design, it (almost) can’t get plugged, because one side will always be open to allow a drain to the suction side of the Pump. Gutter Gaurd was then rolled up and stuffed into the inner diameter of the standpipe, so nothing (big) gets sucked in. The End was capped with a standard black bulkhead strainer.

If you want to re-design yours, I’ll help you build one like this if you want. All It takes is PVC, paint and a Dremel with a cut-off wheel.

My closed loop is a hang over the back type. The return is a 1-1/2" piece of PVC that has a PVC tee on the suction end with a strainer on each side of the tee.
