I was going to post on the Angelfish, but decided it would be best under my own thread.
As some of you already may know, I've got a 29 gal
setup with a single 2-3" goldfish (fancy Ryunkin at that). These fish don't like to be pushed/pulled around too much. In my tank, I have two HOB
filters. One is a Penguin 100 and the other is an Aquaclear 200 (together, cycling water just over 10x at optimum performance). Now, having two, I've noticed that there is more current and more suction being created.
My goldie is an all around tank guy. He's not a bottom dweller, mid dweller, or top dweller. He likes to go all over. What would be the best intake setup for the pumps? Both low, both high, or one low and the other high? Right now I have the AquaClear 200 with a high intake (top of the tank) and the Penguin 100 with a low intake (nearly down to the substrate). It doesn't seem to bother him much, but he does seem to struggle a bit more with swimming the closer he gets to that corner of the tank.
I'm thinking of getting some high background plants to place in that corner to try and break it up, but at the same time, I'm afraid more [fake] foliage in that corner may give him more of a reason to head on over and check it out.
I'm not really worried about him because he knows better than to hang around and he's capable of getting out, but I just want to try and open up more tank space for him to play in without too much trouble. Am I just worrying too much about this?
