I have 3 males. A King Kamfa, Bonsai Fader ZZ and my ZZ. Lots of females. I ordered a few more imports so I had to make space for them. Probably gonna build a 60 gallon rack system for the living room.Do you have two male flowerhorns? Nice setup. I hate doing water changes on one 20 and one 40 I have. I don't know how you and so many hobbyist do it.
Water changes are my peace. I love to see my fish thrive. So I do 5% a day, 25% once a week, 50% once a month on all tanks.
I realize cleaning these racks are gonna be a pain so I left them substrate free and will utilize a water polisher on each tank.
I'm thinking of buying a large plastic water holding unit and start aging my water. I'm sure I could rig up something fun.
