So here's my dilemma.
I have an 8gal with quite a bit of filtration and current. The inhabitants do fine (tetras and cories). They have figured out it's kind of fun to zoooom through the current and do loops around the driftwood arch and then rest up in the terra cotta pot... and do it again.
Time to upset the status quo: I rescued a female betta the other day... so now I need to figure out how to get her a low/no-current area in my 8gal because I don't want to keep her in the betta "tank" any longer than I need to (aka until it's established she isn't sick- so far it looks like she just needed some good fresh water...)
I've thought about attaching sponges to the outflow and intake to slow the water rate down- a possibility still but I'm not sure if a regular kitchen sponge would work or would have been treated with something not so good for the fishies... or if it would break down at some point and I would have to be cleaning little bits of sponge out of the tank and filter (ugh).
My dad suggested somehow creating a barrier at the water surface that drops down 2-3" to create a 'breathing/hangout spot' for the betta. I'm still thinking on how to accomplish this. There's one corner that I think would work pretty well with this idea, I'll try and sketch it out.
I can't use the soda bottle trick- it's not a HOB
filter... the media is horizontal in the tank lid- water fountains on to it through a tube with holes that rests above the media. I'll work on pictures. It's a Jebo R338 with a flow max of 400L/H if that helps. (Came with the tank kit... otherwise I would just replace it with an adjustable filter, but the tank lid is designed around it so it's a last resort really.)
I am working on getting a lot of tall plants, hopefully ones that have ends that will be long enough to clump/pool at the surface... so that should help provide a still-er betta friendly area, correct?
I would rather not cut my filtration if possible.
Sorry if this is ridiculously confusing... let me know and I will try to clarify...
A second tank is not really an option unless the betta just doesn't get along with the other fish.
