Situation is, I currently bought a male starlight bristlenose pleco (or at least I thought it was), this is the only fish I have added in about a month maybe more, about two days after introducing him to the tank I noticed my chain loaches where 'flicking' off of my slate alot on closer inspection I realised they were covered in tiny white dots, I recocnised the problem immediatley or so i thought.
I started treating with Protozin, any white spot trouble I have had in the past this has shown good results within a couple of days, but this is my second day of treating and I have dosed the tank, once i had finished i examined my fish to see how they were getting on and 4 of my chains are missing and alot of my fish have lost colour and movement is very rare. My royal pleco is now infested, well from what i can see any effected fish are completly covered. The spots looked a bit bigger than normal ich and swollen but they have now shrunk and look the way ich should but the fish that are getting it now have the same problem, larger spots that are swollen slightly.
Since i have started treatment the problem has begun to look like ich, but is there another parasite/fungus infection/bacterial infection that the symtoms would resemble ich?
Yes the tank is overstocked (in my opinion) but it hasn't been for long and I am ordering a 5x2x2 foot tank at the end of the month. I have been looking for a bigger tank for ages and finally found one.
Stats are always fine; Amonnia-0, NitrIte-0, pH-6.9-7.1, NitrAte 0-5 (planted tank).
I am sorry about the length of the post but I wanted as much info in as possible so I can get the problem sorted out before I start losing fish.
