Welcome to AA! Kudos to you in providing your betta a 10 gallon tank! It is certainly better than those tiny betta cubes that generally go unfiltered with no heater in the cooler months.
A 55g is a nice acquisition, too. You'll have plenty of real estate to explore in terms plants and aquascaping. I'm personally a planted tank enthusiast myself. You can usually find me and a lot of other experienced planted tank folks in the planted tanks sub-forum here in AA. So when you're ready to get that 55g planted, make your way there so we can offer more help (if you like).
Might I suggest in the interim, that you research differences between low tech and high tech planted tanks. Lighting (ie. LED
vs. T5HO). Plant species that are appropriate for those given light levels. Fertilizers, substrates, CO2
, etc. And calculating light with PAR verses WPG
(watts per gallon). It's good to get a headstart to avoid headaches and issues (i.e. algae or plant deficiencies) later on.
Low Tech is a good starting point that is forgiving and you can learn a lot from. Less work, maintenance, ferts and no CO2
supplementation. If you find that planted tanks are your interest and you're in it for the long haul, high tech is a nice goal to work up to. Either which way, we're here to help.
