Much easier to go Bare bottom IMO.
Learned it the hard way. . .
Go with something 55-75 gallons. Since they will be moved to a 100 gallon planted tank later on I would do the 55.
Feed them 5-6 times a day with good quality foods such as freeze dried blackworms, beefheart, and pick a good flake food. Daily water changes, 50%+ try to do 75%. Wipe down sides of glass every other day.
If you are dead set on the planted tank idea then read up:
