Hi

I am new here and I would just like some help with my Otocinclus. I got him 2 days before Valentine's day and it looked as healthy as it can look. I have been feeding him/her blanched cucumbers, not every day, I leave the cucumber on the tank for 24 hr and I have seen that the Otto really likes it. But today I saw 3 white spots and I am new to taking care of Ottos so I don't know if it is a bacteria. Truly hoping someone see this and can help me. I got him on a 10 gallon tank and his tank mates is a female guppy and her babies that are big enough to not be eating. Water is clean
