I'm finally out of college so I can upgrade my little betta from a 2.5g to a 15g! Right now it's heated and sometimes filtered (I only turn it on after a water change; the current is too strong for him and I never had the chance to get a better one. He's totally fine though. A very happy fish). I plan on fully planting the tank (water wisteria, java moss, java fern, and some dwarf anubias) and maybe adding 3-5 albino cories.
I know I'm going to have to get a different filter and heater.I read cories like current, but I'd only have a very, very, very gentle current. Would the Whisper 30 Power Filter be good? And what adjustable heater would be best? I often see Hydor 50 watts being suggested...
One last thing. Bruce Wayne occasionally knocks himself up or bites his tail, especially after a big change. Would bettafix negatively affect the cories and/or plants? Is there an alternative that would keep Bruce just as healthy and everyone else okay too?
Thank you! I'm very excited to get started. :D
