No Fat people are just Fat........its what they do to correct it or what they don't do to keep getting/stay fat.
Same as in your tank.......its just too small. Now its up to you to upgrade tanks, get rid of some fish or just let them be in poor health or die. One of those Goldfish will out grow the 25. so I would say that more than one is too much.
now if you don't have the means to buy a VERY lare tank in the near future and you don't give them up you can at least do a lot of water changes to minimize the harm that is going to be done b/c of the crowding.
What are your nitrite,nitrate and ammonia readings?
