Hi y'all. I've been searching for some info here and I may have missed previous postings about this. I currently have male bettas - 1 in a 10 gallon and 1 in a glass pitcher. Long story short: tried a tank divider, disasterous results, not gonna go there again.
Anyhoo, because of budget concerns, I'm selling my 10 gallon set up
and using that $ to get two 5 gallon tanks, so everyone has a chance to stretch their fins. I want to stay with filters and heaters, but I can't find much info out there on HOB vs undergravel. Are there any advantages and disadvantages of one type over another? Years ago I had some bettas in their own 1 gal tanks with undergravel filters, but I can't remember anything about the tanks and I want to give them more room.
Any thought would be appreciated.
