Please help...since going on holiday (fish feeders and a friend looking in every other day) we have been having problems. We had a stable tank, good water quality and 11 neons, 3 swordtails, 5 silvertips, 2 gouramis, 2 female bettas, 1 plec. Now we have lost 3 neons (1 awol, I floating, 1 swimming upside down), a silvertip tetra and yersterday a female swordtail (looked like flexibacter) in the space of a couple of weeks. Our water parameters have gone haywire (ammonia and nitrite way up) and today we lost a danio. We have treated the tank with interpet anti-internal bacteria no. 9 (2 doses done).
Also, our danios are really fat, and seemed to have stretch marks on their bellies...today one was alive and within 20 mins of us being away from the tank, was dead and looked like it had exploded. The other fish couldn't really have attacked or eaten it given the timescale. This one was in a tank on its own with other danios and a silvertip and after it died there was lots of stuff in the water (suspended dots). Is this an infection? We have another extremely fat danio...help! Should we keep her out of the main tank? And what can we be doing wrong?

. Could you give us a bit more info, this might help to figure out what the problems are.
