Itís only a small tank, 20 litres, with 2 goldfish. I have a small filter that trickles water back in like a little waterfall, itís on about half speed, just enough to put some smaller air bubbles into the water to the bottom for aeration without too much agitation. The tank has been set up since Xmas day, when the fish was born, his little pal died from swim bladder so I added a new goldfish about 8 days ago, but it died 2 days ago suddenly overnight, not sure from what. The ph is 6-7, no nitrates, no nitrites, no ammonia. I use API StressCoat, & StressZyme. 2 small feeds a day. I do 25% water changes every 5 days, gravel vac every 2nd water change. I also have another 20litre tank full of 9 mollie & 5 guppy fry (I donít have any males, so my 5 females were pregnant when I bought them) I have a 50 litre main tank, all tanks are looked after the same way & all are doing well - except for the goldfish- I thought they were quite hardy?
