Ich is an opportunistic infection from fish stress, so eliminating the source of the stress is important.. whether it be water quality or whatever. Velvet is the same.
You've been treating for 3 months?! What have you been using coppersafe this whole time? It's too long on this harsh med.. Velvet would have been gone by now, but this med is no good for ich.. A complete change will be needed to remove the meds because your filter won't remove them, and 3 months is way too long to use this so it needs to be removed now.
Can you share more A white spot is not velvet. Ich looks like a sprinkling of salt.. I don't see anything wrong in the photo you posted.
I agree, in the future the best treatment for ich is raising temps slowly at 1 degree per hour into the 86-88F range. Leave it there at least 2 weeks and one week past the last sign of ich. You can also use aquarium salt at 1 tsp per gallon for up to 10 days. It will need to be predissolved outside the tank in some of his tank/treated water before adding. You only need to add more salt along with a water change, and then only add as much as water you change.
On a regular basis he is a little chilly. I would adjust your heater into more around 78-79 range.
The problem with relying on your filter in such a small tank like this is that it is very hard to maintain the biofilter, if not impossible.
Most people will tell you that you can't ever fully cycle a tank this small, despite your filter, and you will alwys need these changes.. you can try, but careful daily monitoring and reliable test kits should be used. You need to be testing daily with a reliable drops kit for ammonia and nitrite and doing an extra 50% change any time you see either. In addition to this a weekly 50% with siphon or new fresh turkey baster that has never seen chems is needed to remove poop and other debris from the gravel. It is not enough to just scoop water off the top ever. I actually suggest a turkey baster or very small siphon because your tank is so small an average siphon will remove water too quickly.
First you will see ammonia, then nitrite. Eventually, hopefully, you will see ammonia fall and stay at 0 even after a week of no water changes, and finally nitrite. At this point you will be left with only nitrates after a full week of no changes and these can be kept <20ppm by twice weekly 50% change with baster/siphon. However, cycling will take up to two months to complete and many if not most people will tell you that you can't cycle a tank of this size and you will always need twice weekly 50% and 100% water changes or you will always see ammonia continuing to build and the cycle will never finish..
Also any time you replace all the media at once in your filter it restarts your cycle, so if your filter only has one type of media (like a single bio bag) this is a serious fault of your filter.
IT's true he should be fed 6 days a week (two meals a day) and one fast day. You should look for a good quality pellets whose first two or three ingredients are whole fish, not fish meal or wheat. How many you feed depends upon your betta and the pellet size.
