Hey guys I am new here! A little background I have not had a fish before at all! My boys and I got Finley the fish last week he is a male twin tail half moon Betta! Now today I came home from work and saw foamy looking clumps of bubbles by the filter and starting in one corner of the tank and was wondering if I am having filter problems or if he is building bubble nests?? I am doing my first partial water change tomorrow!! Any helpful hints would be appreciated as well!!
