Guest iat814 Posted October 23, 2008 Share Posted October 23, 2008 (edited) My friend has a 20 gallon high tank (LxWxH: 24" x 12" x 16") which he keeps four one inch goldfishes. The fishes don't look too happy or swim much. In fact, the two bubble eyes are sitting on the bottom of the tank most of the time. He runs a AC 50, so I assume that is just about enough filtration. His levels are all normal. What can I tell him to do to make the fishes happier and more active? Edited October 23, 2008 by iat814 0 Quote Link to comment Share on other sites More sharing options...
Regular Member Tinkokeshi Posted October 23, 2008 Regular Member Share Posted October 23, 2008 with a 20 gal tall, the goldfish will probably need more aeration. not as much surface area in tall tanks as opposed to wide. does your friend have any bubble wands? or other means of putting more oxygen into the water? if not, that might be something to try. also... how often does he do tank maintenance? actually... now that i think about this, i'm going to move this topic. 0 Quote Link to comment Share on other sites More sharing options...
Guest iat814 Posted October 24, 2008 Share Posted October 24, 2008 He does run a bubble wand the length of the tank. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member alexiscool Posted October 24, 2008 Regular Member Share Posted October 24, 2008 If he wants them to be happer then he will need to get a 40 gallon with a filter that runs at 400gph or get another 20 gallon and spilt them up. 0 Quote Link to comment Share on other sites More sharing options...
