Hello, so in my dorm room I have an oto, a betta and a snail in a 3.5 gallon tank. I will be going back home from March 20th to the 30th. So, my question is: would it be alright to leave the oto and snail alone in the tank while I am gone? I'd rather not bring the entire tank to and from as not to stress the fish, so I plan to leave them in the tank and bring the betta back with me in the smaller container I bought him in. I have algae wafers that I was previously putting in the tank for the oto, but my betta started bloating and I found out that he was eating the wafers, so I stopped putting those in because I don't think that the oto was even touching them, but even without them my oto seems nice and fat (see picture). So, if I clean the tank and leave an algae wafer or two before I leave would this be possible?
