We are thinking about getting a larger aquarium. We liked something at one of the LPS that is 34 gallons that we'd like to split in half. I've been mulling over what kind of divider to use: something solid or something mesh. The advantage of using a mesh divider seems to be requiring only one filter and one heater. The advantage of using a solid divider seems to be eliminating or greatly reducing passing infections.*
We have one veil tail male now in a 5.5 gallon, heated and filtered tank. I do not intend to use any live plants if we upgrade to obscure their views between the divider. I will come up with something else.
I gladly welcome all opinions!
PS - We will either split it in two and have bettas on either side; or split it in two and have our betta on one side and some kind of grouping on the other side; or we might split it into thirds and have three bettas, one for each section.
