hey whats up i had needlenose for a bout 5 or 6 months and i cleaned the tank to day like a usally do i do nothing defferent and he did't seem any more up set then he usally is when i do it but when i was done i left of about an hour and then came back and noticed that he was kinda not acting funny but i did't think nothing of it but then he was kinda floating weird so i got kinda worried and i grabed him and kinda held him for going belly up but at this time he is'nt giveing any fight or anything then about 10 min of holding him he died and i have no clue why it kinda makes me mad because i think it is my fault because i cleaned the tank. well i had him and a freash water barracuda and now he kinda is acting funny not like he is going to die but like he is sad or somthing could this be true they where pretty good friends they where right next to each other all the time. well let me know what u guys think it could be thanks.
