So I have been thinking about how to make a fuge but not have ugly hoses coming into the tank. It occured to me that I could use a jar or a bottle with a plastic lid inside the tank. The jar or bottle would have ventilation holes in the top which would be big enough for pods, scuds, etc to escape in small numbers, but small enough that fish cannot get in. It would then get a sand/soil mix for substrate and some rock on top. The jar would be small enough to hide behind plants and rock towards the back of the tank so as not to be obvious when viewing it from the front. I would need to be able to access it easily though because the pods would still need food and water changes every so often. I am going to do a search to see if anyone has had success doing this. Surely I am not the first person exactly to have this idea. I know I have cyclops, scuds, and ostracods in the grow-out tank and a few nematodes here and there. If anyone reading this has tried this idea I would love to hear your experiences with it.
