Upgrading from 20 gallon to 75 gallon

Hi everybody! I've had a 20 gallon high tank for several years with a Fluval/Aquaclear 20 gallon HOB filter and a Fluval/Aquaclear 30 gallon HOB filter. There's CaribSea sand substrate, fake plants and fake logs and caves. For fish I have 4 harlequin rasboras, 3 spotted cory's (Corydoras ambiacus), 2 otto's, and a single electric blue dwarf ram cichlid (who killed his friend but mostly leaves the other fish alone).

I have a new empty 75 gallon tank, 48 inches across, 18 inches back, and 20 inches high. I got a 48 inch Marineland aquarium plant led light with timer (and an extra Marineland single bright led 36 inches I can add if necessary). I also have a fluvial 306 canister filter which I know is only rated for 70 gallons but I'll add one of the HOB filters from the 20 gallon to get the nitrogen cycle started. I haven't put anything in the tank yet.

I want to have a good number of plants and some driftwood in the tank but I've never had plants before and I have a limited budget (also I'm not good at DIY) so I'm planning on getting pool filter sand and then supplementing with root tabs, I don't want to mess with CO2.

Ideally I would take all my fish from the 20 gallon and put them in the 75 with some fish that would get along with them, I'd like as many varieties as possible but very peaceful, I hate to see fish fight. What are some good plants for me to start with and some interesting fish. I was thinking maybe I would eventually get discus but they seem pretty high maintenance and I heard angels can get aggressive, so maybe Bozemani rainbows, or rose line sharks, or rummy nose tetras, black neons, maybe whiptail catfish? Is there another centerpiece fish that would get along with my dwarf ram like a Bolivian ram or should I leave him and some of the others in the 20 gallon, I would like maximum flexibility but definitely want some cory's and some schooling fish. Thanks in advance for your thoughts!

You might take a look at the procedures in my signature.

which are worth at most .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

I can't say much for the fish as you have far more experience than I have, but I'll share what I've got.

If you like how it looks both anacharis and scarlet temple are fairly cheap and easy to propagate. When they get long enough just clip them, use sinkers attach bunches of them and put the cut end right in the sand. They'll root and grow until they're ready to trim as well. Moneywort and Green Cabomba are similar. Anacharis grows like crazy. I don't recommend clown loaches with live plants as they tend to rip the leaves off and rearrange them if they aren't sturdy.

I haven't had any luck getting hornwort to root after trimming. I've not had much luck with carpetting plants either :/

Amazon sword gets pretty large, very nice leafy plant with a large root network. I have no experience in propagating them.

Jungle Vals get huge. They look nice until they start stringing across the top of the tank. Mine were about 4 or 5 feet long before I trimmed it. There's no real harm until it starts blocking the light from getting down to the other plants. So there's a bit of maintenance on them. They propogate from their roots so its harder to tell when they're ready to make more.

Aponogeton takes awhile to propagate, but does so on its own with young growing from the leaf tips. Same with java fern.

Just a small fish in the great big sea.

All the fish from your 20 gallon should do fine together in the 75. I would increase the harlequins to about 10-12 and increase the cories to 6-8. I personally love Rummynose and would do a shoal of about 10-12 of them also. For a centerpiece fish maybe a male Pearl Gourami.

150 Gallon - Mostly American Cichlids
135 Gallon - Angelfish Community
75 Gallon - Odd couple (Polleni/Angelfish)
55 Gallon - African tank
20 Gallon Long - QT
10 Gallon - Empty

I have ludwigia rippens growing in sand quite well.
P.s. There are too many plants out there to buy that played out petstore special. Pm me if you want the webpage I order my plants form (I don't own the page nor do I make any money from it).
