So I've been a pretty bad betta parent these past couple months and haven't changed my Betta (Neptune)'s water.
I just changed it out, added anti-chlorine chemical and have fed him. He's been very sad recently and just lays on the bottom of the tank, floating side to side and generally being depressed. I want to help him recover as quickly as possible but have a few questions before I jump in.
1. I want to add some aquarium salt and a general fungicide to the tank to make sure opportunistic diseases don't take hold. If I've never had these in his aquarium for his 2+years of existence, will it shock him? Is it ok to start adding these things?
2. I want to start vacuuming his 2 GAL tank, is there a recommended vacuum for this size of tank?
3. Anything else I can do to help him? I'd love suggestions.
A little background on Neptune: 2 Gallon tank home, water isn't changed super regularly, once a month at best usually a bit longer :( Eats pellet food. Has a live plant in the tank. Small water heater. Small water filter. Was generally happy until about a month ago.
