My brother bought me a 15 gallon Top Fin fishtank for Christmas this year. It's a starter kit that has it all - the light, filter, sample foods and conditioner, etc. What I need to get is the decor, gravel, dividers, and the heater.
I have three bettas and I think I am going to put two in it. They will have 7.5 gallons to themselves that way. I have numerous questions if you guys will be kind enough to help me.
Can both sides of the tank successfully be filtered with a divider? Because I am under the assumption the filter will be placed one one side so I am wondering if the side on the other side of the divider will be filtered well too? I am afraid only the side I put it on will be taken care of and the other size won't do good. Or should I put a filter on each side? This is what confuses me the most.
What are some recommended chemicals to put in a big,filtered tank? I am going to use water conditioner when I first put water in it. What else will it need?
I also heard that filtered tanks only need about a 30% water change once a month (or was it every two weeks?) and little vaccuming on the gravel once or so a week. Do I have my facts straight?
Also, is there one or two other fish I can put in with them since they are roomy? Maybe I could get each betta a small tankmate. A type of tropical fish they'd get along with and don't mind being solitary. Or even if there are something tropical that are tiny and can live in small groups with them? But if you guys think they'd be better off on their lonesome, that's cool too. I'd just like to get something else if you think they'd get along fine.
I am thinking about getting some real plants. I heard they like the kinds that float at the top of the water so they can rest in them. What is it called?
Do you guys recommend the dividers at Petsmart, even if you have to cut them to fit?
I think that's it for now. I'm excited about this tank and I can't wait to get it set up! I am getting a stand for it tomorrow and the heater and divider, and whatever else is recommended. I'm sure I'll have more questions before it's over.
Thanks in advance, guys.
