I've got a ten-gallon tank with half a dozen diamond tetras and two sterbaI corys in it. The corys were just introduced from quarantine yesterday and one of them had slightly pink gills so I was advised to get a bubble wand so as to increase the aeration of the tank (the ammonia levels etc were all fine). Anyway, I got the bubble wand today and, even with the smallest available pump, there's a **** of a lot of bubbles and the fish don't seem too keen on it at all!! Are wands really necessary in a tank this size? Is there anything actually WRONG with having a bubble wand? Or should I be patient and see if the fish warm to it? Thanks guys!!
