So my fish got sick and I am wondering if it is because there wasn't a filter. He started showing signs of finrot and clamping so I move him from a 2.5 to a one gallon and started treating him with green tea and aquarium salt and daily water changes. He has been on treatment for 6 days now and is improving.
I don't know what was wrong because I have been doing 100% water changes every 2-3 days in the 2.5 gallon. I had to get a new heater because the temperature was only keeping around 76 degrees. Maybe this contributed to his health issues? So I bought an adjustable heater that keeps the temperature 78-80 degrees now in the 2.5 gallon tank.
Other problems I've been having are issues with the plants. The java fern seems to be getting brown and clear leaves. The anubias leaves also appear to be 'melting'. Lighting should be sufficient, it's a 27 watt 6,500 k over 2.5 gallons. I dose with Excel (carbon source) and API Leaf Zone Plant Food. Plants are not buried, they are tied to a piece of driftwood and a rock.
So, I am wondering if a filter would help my fish's and plants' health. Maybe the water isn't getting circulated enough and is causing problems for everything? Maybe, it's too much organics sitting in the water? I don't know but I would like to avoid any further problems and not have to keep buying plants.
So what filter is good for a 2.5 gallon tank? I really don't want to put an internal filter in the tank (I don't want it taking up precious space). I prefer the HOB filters but couldn't find one recommended for a 2.5 gallon that houses a betta. So, what do you guys and gals use? Until I find something, I'll probably keep my betta in a one gallon with daily water changes. I don't want to run into finrot issues again.
I really wish I had bought at least a 5 gallon tank now, but unfortunately I have to use what I have. MIFF!
