Ok perfect! Glad I asked otherwise I would have gotten the 30 gallon. I am going to probably get an adjustable heater for the tank so I can find a good temperature that is good for all the fish. If that’s good
I've been thinking, the 20g filter might be best. These are adjustable, so you cold turn it down. Yes, I think the 20g over the 10g. The last heater I bought was an Eheim Jager. The calibration was off, but that doesn't matter, many of them are. I set it at 20C and it kept the tank at 25C, which is all that matters, stability.
