Re: xipho issue ( im using interpet swimbladder treatment )

Hi there, lets hope FK can help given the time lapse between our countries
By Xipho, I assume you mean what we normally call a swordtail; linky here for you to ID
http://www.seriouslyfish.com/species/xiphophorus-hellerii Has the tank only been recently set up? I do wonder if it could be water quality. What test kit are you using, strip tests or a liquid one?
The tank temp concerns me for the goldfish. 28 degrees is much too warm. He could really do with a chiller unit/fan.
Other thoughts that immediately come to mind are:
Tank size - the tank is very small really as Nathan has mentioned for the fish you have. Fancy goldfish need 145 litres for one fish, larger if you want to accommodate a buddy. They are cooler water fish. 120 litres lends itself to some trop stocking well.
Tank mates - most here in the UK would not add other fish to a goldfish tank. From an aesthetic point of view the others are warmer water (trop) and need generally higher temps than the goldfish.
We have had posts here too where goldfish have tried to eat other smaller fish - one with a cory which was absolutely awful as the fish got embedded for days in the goldfishes mouth due to it's spines. Goldfish are therefore generally kept to species only tanks.
Water Hardness and pH - not all fish suit the same type of water. Some need quite soft and acidic water to thrive such as your plec and cory. Others need harder, more alkaline water i.e. the swordtail, platy and goldfish.
Do you know your tank water pH and GH at all?
Your stocking ratios seem a little out. Whilst this wouldn't cause death per se, it will cause stress which can cause a fish to become ill over time. The Cory for example are shoaling so should be in a group of at least 6, the platy and swordtail are livebairers and ideally need a stocking ratio of 1M:2F to avoid the ladies getting harassed to death.
Apologies, quite a bit to take on board but I hope this helps. Personally I wouldn't be adding meds until tank water quality, pH and GH issues can be ruled out. Daily water changes in the interim will do no harm.
Swimbladder is not a disease but a symptom of many types of illness and the above need to be addressed to see if any of these issues are triggering the illness really.
