So, I have this 10 gallon freshwater/tropical aquarium. I finally got it set up and running, so the water can get to where it needs to be. Any suggestion of how long I should let it go before adding fish?

I haven’t gotten any fish for it yet, since I wanted to make sure the water was just right before adding them, and risk killing them…
And I have some fish grouping ideas, and I’m sure when I go the people at the store will be able to help me…
But can anyone on here give me what they would put in a tank that small? what fish? What plants? What decorations?
I want a “showcase” fish in there. And when I say showcase, I mean one that’s slightly bigger and brighter than all the others around it. I’ve looked at gouramis and I like the dwarf and honey gouramis, so if I can’t find anything else to my liking I might get one of them to go in there. But does anyone have any other suggestions? Of bigger colorful fish I could center in my tank? And what smaller ones should I put around it. I was thinking maybe 2 cory catfish, and few platies, and maybe even a couple shrimp or another small school of fish… I can’t really make up my mind there… So any suggestions should help!
And yes.. i know I have to be careful about putting in to many.

Another topic. I have a Betta. He lives in a 2 gallon fish bowl. He’s fairly docile, and even though I’ve shown him his own reflection and other male betta, he doesn’t puff up or act necessarily aggressive. Do you think he could live in the 10 gallon? I’ve heard it possible he could get along with the community fish, but not the gourami. Do you think with his docile demeanor they could potentially get along? Or would the other fish be more likely to attack him. I probably won’t try this, but even if I did I know what keep an eye out for fish attacking other fish.
If I can’t, I would like to get something to heat up his fish bowl. For the time being it does not have one, but I know they are tropical fish. So far, the cooler water has seemed to affect him at all, he’s moves quite a bit, and eats regularly. It probably has to do with the fact I keep my house warmer… But it’s starting to get colder and I’m worried.. I don’t want him to be too uncomfortable. So do they even make heaters for bowls? and if they do how much would they be?

One last question. I’ve been really interested in getting another aquarium. I LOVE marine fish. How exactly hard is it to get a marine tank set up? What are the steps involved?
It’s something I’m highly considering, but will have to wait on. But I KNOW I would love at least a pair of clownfish if not more. What are some other good, BRIGHT COLORED tank makes for them?
I also don’t want to big of an aquarium in my house or I won’t have room for it… So how many clowns and how many of another type or two of fish could go into a 30-40 gallon tank? How about a 50 gallon? How expensive is it to turn one of those into a saltwater tank?

I hope I can get some good answers here! I’m honestly curious! I’m sorry I have so many question in here, I hope someone can answer them all!
But thank you!
Oh! I thought of another question!
If I do leave my Betta in the 2g bowl, is there enough room for a dwarf african frog, a snail or 2, or even 1-2 female Betta? Any room for anything else AT ALL? Thanks!!!

Now what was Ideal for me was to only have 1 gourami and 3 balloon mollies and the neons and I really want some red cherry shrimp. Do the shrimp count towards my stocking count? (That may be a dumb question.)

Could I add the balloon mollies and some red cherry shrimp without overstocking my tank? I would really like both but if I was in danger of overstocking I would reconsider my purchases. Could someone help me out?
I already have the 3 gouramis and they are very small no larger than an inch. The two neons are fine together and i prob should get some more. I will prob. do 3 mollies but i just wanted to know if the shrimp would over load the biofilter or not.

However, i have never owned a Betta, or a Goldfish, though i have an idea of how to treat them.
But I have never owned a mini bowl tank. Unfortunatley, i have received a “betta bowl” for xMas, that looks similar to this in terms of size:

Given that I will make use of it, probably putting my first Betta in…

~~~First (set of) question:~~~
How does it really work?
As in, would you even cycle that?
Would you bother putting gravel in it, i’m planning to have horn wort in it, which doesn’t necessary need gravel.
How do you do water change? I don’t think vacuum cleaner is an option. It’s so small too, wouln’d pouring water in and out so stress the fish?
And given how small the bowl is, how often do you change the water?
My room is quite cold in winter, maybe 10-15 celcius? You can’t put a heater in that thing.
Right.. i really dont’ get how those stores can have maintain those cups of bettas…

~~~ Second (set of ) questions: ~~~
Please don’t kill me, but on the box, it says don’t get mistaken by the name, thought it’s called “Betta Bowl”, you can put a golfish in.
Now i’m pretty surprised, i thought Goldfish needs BIG tank for how messy they are. So I think it’s lying.
But in case i’m wrong, do you know any kind of GOldfish that can be happy in that bowl?

THanks!
