I have a 30 litre tank with a rock, 3 live plants and a little gary ornament. I have a little fishy ( called sugar) that is chubby with a long tail ( but not like veil tails)variety had Sugar for 8 months on friday. But recently she has been ill for the first time. first she just looked a bit out of sorts. then it developed into swim bladder. I treated it and she was fine within a few days, but then she got fin rot. I put in the treatment then I went on holiday. I came back yesterday and I thought she was dead. But then she stared swimming again but turned upside down. She can't stay upright because her fins are so small from fin-rot. One is bigger than the other so she just flips. I have one other goldfish that seems very healthy. It isn't a common goldfish but isn't a really fancy variety either I have had it for about, a month. I got a sucky fish at the same time & that was fine this morning but has suddenly died, I had just put some "disease safe" that is supposed to treat various things, I am worried that that is what killed him.
Sugar also has a black spot on one side now. She can't swim and just stays still upside down, then tries to swim a bit. I have another tank should I use it as a hospital tank? & if so I dunno if I should put both fish in in case the water is dodgy , or just the sick/ healthy one.. :/ & the empty tank has no water or gravel in or anything, should I transfer some stuff out of the tank or might I contaminate it..? & would it be ok to rinse it with tap water first?

sorry it's so long. I'm really worried :S Btw I am going away again tomorrow till friday.
I do have a filter, its a sting ray, carbon/zeolite.
It was an Algea eater. & the problem is tanks are expensive, & I spent the last of my money on treatments :S .. They are very small, for the moment, for end of tail to end of head - 4 cm & 3 cm normally. I think I will try to save up and buy a bigger tank.
Thank-u all for answering xx
 
do you have a filter?
that tank is much to small for one goldfish let alone two. if you didn't have a filter they were probably stressed from to amount of ammonia in the water and stress hampers there immune system so they succumb to disease. unfortunately i don't think your fish will survive. if you want to keep fish again i would get minnows and a filter. i got a filter for my tank for 20$
you can try and help her by adding melafix and buying a really good filter and doing daily water changes of about 25%
 
keeping that fish alive will costs u loads of money i think its time to let him go the fish is very ill and its sad to keep him alive he could be in pain if he does die treat ur tank and disinfect it all ur otherfish should be fine im sorry about the one tho ask me if theres any other signs if there is a black spot where they have babies from ur fish might be dyingcause of its babies it happens
