Don't rush take your time.
This is a good amount of plant thickness. Don't rush it takes a couple of months for a tank to grow out. Have floating plants for hiding on the top.
This would be a goal for offering cover for your girls. This tank is nice but you can do a jungle look and your girls will like it. Do a thirty day quarantine. People will tell you 14 is enough but after 2.5 weeks one fish got sick. Had I rushed the whole tank would have been sick and my plant money wasted. Keep the girls in sight of each other the whole time rotate positions. I kept mine in a close circle. I took two months to get my tank going snails went in first. I have one mystery snail that is really effective for cleaning the tank and she innitially helped to provide fertilizer for my plants.
When it's time to put them in float them in cups in the tank for 3-4 days to get them used to seeing each other in the tank and use the tank water to change the cups. Make sure the cups are stable the cups can turn over. Have a breeder's net and use time outs for excessive chasers. It took a week of confinement for one girl to behave. Some people have to repeat the process another week. Some girls just won't work out have an extra tank just in case. Keep your gallon containers in case of sickness. Have basic meds on hand in case of sickness. Especially if you can't get them locally.
Make sure you can be home at least a few days when you are ready release them observing them is really important. Test your water frequently water quality is important. Everything I am sharing was given to me by others on this forum. It really helped!
