Hello all,
My dad passed away last November and he had a few fancy goldfish left in a 20 gallon tank with a millenium 3000 filter. Well we didn't know how to take care of them except feeding them daily. Slowly they all died except for a single black moor. the millenium 3000 filter broke down... impeller spins and there is motor noise but doesn't suck any thing up the siphon .... I bought another aqua-tech 20-40 from wal-mart and using that now.
I start reading these discussions and find out about ammonia, nitrite, nitrate levels and water changing and started changing water on tuesday 2 gallons, then wednesday 2 gallons, and then friday 2 gallons... next would be on sunday, before doing the research I did a full tank water change once a month.... i know this probably lead to the other fishes dying ....
The reason i did the research is because the Black moor is now swimming upside down but not really floating to the top so I am not sure if it is swim bladder disease or not, he's the only one left and i don't want him to die... so I didn't feed him on friday and gave him green peas this morning hoping it would help, but he's still swimming like the video below.
I'll get a ammonia test kit today and I'm waiting for my gravel vacuum to get here but i'm just amazed my dad didn't need any of these things to get the gold fish to those size (he had a lionhead, fantail and some other fishes in there). I also read online that you need +10 gallon for every fish you put in a 20 gallon tank, well he had at least 5 fish all those sizes in a 20 gallon tank and they were all healthy .. of course till he passed ....
