As a partial follow-up to my first thread, I just recently moved my fish into a new aquarium. At the recommendation of the fish overlords at PetSmart and one overly excited guy in the aisle, I picked up a Marineland 200b to go with my 20g tank. After a couple days, I noticed that my fish refuse to come out of the side opposite the filter unless it is turned off. This seems to be stressing out my red minor tetras, since they stopped eating and are losing their color. The flow from the filter is quite strong, so I'm not sure if just trying to redirect it would be enough. I stuck a net in front of the output to see if it helped, and they started to venture out a little more, but no where near like before. I just turned the filter off, and within 2 minutes they were swimming all over the tank having a blast with all the extra room.
Would something like a Tetra Whisper EX offer similar filtering abilities while having a gentler flow? I know it's a silly comparison, but they seem much happier with the gentle waterfall of my old Aquaclear 20 than the firehose blast of this Marineland beast. If not the Tetra, any recommendations on a good filter that doesn't flow like niagra falls into the tank?
Thanks,
Nick
