Hello,
So I'm thinking of starting a freshwater tank for the first time since I was a kid. I have a saltwater tank and have had one for about 6 years now and on an off for about 12 years. Thinking using a AIO tank, think it's 10-15 gallons, to start since I have one laying around. Let me know if this a good option or if I would be better off with a basic tank with hang on filter or sponge filter. If I use the AIO tank I would prefer fish that can handle warmer water as it would be in my room and it has a lid so very little ventilation. I possibly could do open top, but I really wanted to keep light spill to a minimum. Let me know what you think. Appreciate any and all feedback.
