Thank you for helping me... I've had other fish in the 20h and have always wondered why I need to do extra water changes to keep the nitrates down. It has a Penguin 330 with 2 bio-wheels and luckily there hasn't been a problem with ammonia or nitrites, but now I understand why it is different than the other tanks.
Anyway, if I can find more glass catfish I will not get more than 5 to add to my 3... probably 4, for 7 total, because the ones I have are approaching 3" each and even at that I would be overloading the tank, although I am used to doing extra water changes on that tank. And I will QT and and add slowly, thank you for the reminder.
The driftwood I have will work well in the 20. Do you guys have a better idea for plants than the pothos? And I was thinking of sand (Tahitian Moon) instead of the smooth-edged gravel they have now. I love it in the 50 with the clown loaches.
