I recently got a Betta Fish from a pet store with a 1.5 litre bowl, the woman gave me some stuff to put in the water to take the chlorine out of tap water so i've been doing that. I do FULL water changes every 2 days.
2 days ago I noticed some white specks on my Betta fish so I looked it up and turns out it's Ich. There is no pet store close to me so I quickly ordered a few things online; Melafix, Seachem Betta Basics and Rapid White Spot Remedy - I also did a full water change, added the dechlorinator(?) and added half a tablespoon of SEA SALT. The items I ordered online are due to arrive TODAY, however, when I woke up this morning my fish went from HEALTHY (with the exception of the ich of course) to the IMAGE BELOW. He is lying on a leaf at the top of the bowl so he can get oxygen directly from the air. When I first saw him I thought he was DEAD! How could this happen?
I have been feeding him 3 to 4 pellets twice a day as advised by the pet store assistant, I really just want to know what I should do from this point on!
EDIT: He sometimes lies sideways like he is dead and he sunk to the bottom once, stayed for about 1 minute and dashed to the top again...
EDIT 2: He used to dash at the bowl in a zig zag fashion previous to this, even before I noticed he had Ich. He was VERY active and ALWAYS ate so I'm not sure if this is just him or if there is another problem..
