It is going to sound a bit of a strange question, but does it matter? I've only used Eheim Liberty HOBs, but they would just be able to swim in and out via the outflow?expensive hillstream loach disappearing into my HOB
The trouble is that you can accidentally crush the loach or isolate it behind the cartridge with no return route when you clean the filter. It’s hard enough to catch loach in the big tank as they can lay flat, and near impossible when you find them inside a HOB.Hi all,
It is going to sound a bit of a strange question, but does it matter? I've only used Eheim Liberty HOBs, but they would just be able to swim in and out via the outflow?
It is actually quite a common question on Plec. keeping forums, "Why does my Ancistrus/Panaque etc spend all night stuck to the outflow of my Hob filter?" and I always tell them that they have oxygen issues, and usually they ignore me.
