My daughter and her partner want an easy to look after fish I a betta is a good starting poin but was wondering an ideal tank size for a single male betta.
5 gallons will give enough space for a solo male, but like any fish bigger is better.
I recently moved mine into a 20 with some neons, dwarf cories, and danios and it is loving it.
ok that's good I can give them some seeded media. I am tempted to get one my self such a large variety when it comes to the betta fish I have a 12 gallon cube laying around.
