help!! please

well ok i have four ten gallon guppy tanks and my female tank has come under attack from some type of illness one of my gold females has a large white lump on it i have no clue what it is sorry i cant get a very good picture of it

 

done a water change lately? Look up Columnaris and see if that's a match

here ya go... Flexibacter Columnaris - Disease Profile

 

yes i did a water change yesterday and everything is just fine i dont know it kinda sounds and looks like Columnaris
thank you

 

you're welcome. it's a pretty common thing and way back when I had a fw tank mine had it too......hope your guppies get better soon!

 

Well cuttinggras sorry to say but my guppy past last night i hope this will be the end of this disease. I have another problem my favorite female started swimming around in circle in middle of the tank not slow but not fast just normal last night and when i woke up looked over and saw my fish just floating there. something is not right in that tank but my plecos and cories are fine along with the shrimp so i dont know

 

Wow, I'm sorry to hear that Karma for your loss. What are the results of any water tests you've done?

 

Sorry for your losses man!!!!!!!!!

 

well all good i did the test last night i dont remember the numbers for the nitrate and nitrites but ammonia is at 0, 78 temp, and ph level is 7.0 so i guess everything is fine but i just got back from my girlfriends house looked in the tank and all the fish are back to normal. Yay! thanks for the support. lol
