2 days ago, I bought 7 congo tetras (only ones left at the store, each cost 45 kc/about $ 2) Ever since theyre in the tank, they always hang out in the back, right behind a huge java fern, so I never see them :thumbsdown: they only come out to feed... so my question is, what do I do to make them comfortable? The tank is in my signature... should I get a dark background? Would getting more of the congos help? cause im planning to do both anyway.
Thanks
