Hi guys!
Quick bit of background: currently I own The Dude, a golden albino axolotl who lives in his own 75l long tank, and recently I got Foo, a betta who is doing well in a little 9l tank with no filter (i do a 100% water change every 4-5 days. The tank came with an Aquaclear filter but even with a baffle on it seemed like too much current for a fish recovering from fin rot.) Just the other day I acquired the AR510 (75l) tank with stand for the princely sum of $75 second hand. I've just started cycling it, with gravel and a few plants but no fish.
But I'm struggling to figure out what to put in it! I'm really more interested in a small number of fish (or even an individual) with lots of personality rather than a community tank. My initial plan was to divide it and have a betta and an apple snail in each half; since setting it up I've been wondering about the trickle filter though. It doesn't make huge current but it does create quite a bit of surface agitation from the water coming out of the spray bar and falling through the filter media back into the water. That doesn't strike me as ideal for bettas as I feed mine floating food. Also I'm starting to feel a bit reluctant to compromise the tank visually by dividing it.
I looked into a fancy goldfish but as with most other species I've looked at that appealed to me it seems like this tank isn't really big enough in the long term for even one. The other fish I'm seriously considering is dwarf puffers, but as the lady at HFF said on the phone in a tank that size I'd probably never see them! I would be happy to do heavy planting and create lots of hiding places so that I could have a few in there, but if I never get to see them then there wouldn't be much point!
This tank just seems to be the wrong size for everything! Do you guys think dwarf puffers would work? Or can you suggest something else that would do well as a single fish or small group and has LOTS of personality without being too tricky for a relative noob to look after?
(Alternatively, is it possible to baffle or modify the spray bar to reduce surface current? I gather. A lot of people end up giving up on these trickle filters and getting something else...but as I just forked out for the noodles and carbon pads I'd prefer to get some use for it before I consider switching!)
