So I am going to get these plants, if I can find them
Glosso, Red Rotala, Eusteralis and Vallisneria.
How many watts is the lighting you have? I Havn't used any of the non-pressurized / DIY CO2 options, but I know that Glosso is pretty demanding, and you would probably need a decent light and co2 set-up to get it to grow well.
Also, most vals get pretty tall (they can easily get over 20''), so I'm not sure how they will do in a 10gallon.. I think they should be fine- you will probably just needed to trim them back every few days or so. Another grassy plant that looks nice and grows really fast is sagittaria
. Some of those will only get to be a few inches high, and can look very nice.
#2 Will the Betta be ok with that?
Certainly. Just watch your pH and make sure it doesn't get pushed to low in case the co2 system you are using affects that.
#3 Do i need a heater? (I live in Fla so it is never cold)
How much does the temperature vary from day to night? Bettas are pretty hardy and can get along in colder water even from what I've read, but depending on how much the temperature fluctuates, it might not be bad to add a small heater.
#4 Are there any other little fish I can put in there that would go with all that?(I want like a few of the same..like a little school)
I haven't had any Bettas before myself (only a paradise fish), but I know they are very aggressive. He would almost certainly go after most any other fish you added in. You may be able to add another female beta, but you will have to check with other people on the forum to see how aggressive they are with the females.
#5 Should I cycle the tank with the plants and the fish or wait to add the fish?
I would cycle for a bit with just the plants. What you could do is add something like a plant or some substrate from the tank your beta is in now: that will help seed the bacteria needed for cycling and speed things up some.
#6 is there anything else that I need to know?
Hmm. nothing I can think of off-hand. If this is your first time with planted tanks goodluck! It will be a lot of fun for sure. Couple general tips I would add would be be careful not to get too much
light- don't have the tank anywhere where it will get sunlight, and don't leave the lights on during the day more than 11 or so hours. Flourish excel is a really nice supplement for tanks without co2 as well.
Welcome to the forum, and goodluck!
Keep us posted on how things go.
