;) Thanks for the help! I set up the small tank, heater, light, and filter. And i bought 2 black moors, small only about one inch, and a yellow snail, I am not sure if it is an apple snail or not. I did not find any frogs yet, but I put my betta fish in with them!!! He does go after the moors so I don't know if I will leave him in there of not. I think everyone would be happier if he was out, and then I could get something else. I think the filter I have is to big, I only run it two hours a day but the fish hide behind the plants or look like they are swimming upstream when it runs. I will look for the small filter Amanda uses. Thanks again!
I just want to make a few comments. I don't want to appear to be lecturing or anything but I guess that's the way it seems! How big is your small tank? Goldfish once they grow up need at least 5-10 gallons for each fish. Moors can grow up to about 8 inches with some getting bigger. It will take a few years though. If you have an apple snail (likely since few snails are yellow that aren't except some exotic tropical ramshorns), it will grow to at least a ping pong ball size. Mine is almost the size of a tennis ball. They need big tanks too. Bettas and goldfish aren't a great mix. First, the betta will chase after and rip the fins of the moors since they are kind of clumsy and slow. The betta thinks the flowing fins look too much like other male bettas. Also, he likes it hot (75-85 degrees F) while the moors like it cool (60-75 degrees F). They will also have to compete for food.
Filters should be run all the time. If the fish have trouble swimming against the current, then yes, the filter is too strong for that size tank. Seeing as the tank is small, the filter probably puts out too much local pressure in such a small tank, creating a whirlpool effect. Good filtration is a must but you don't want to spin the fish around like in the washing machine either. Bettas like slow water while goldfish like to have a part of the tank with a little water flow to swim against but moors, being weak, also need a still area of the tank.
Anyway, my suggestion stays the same to get larger tanks for your great fish and snail. Good luck!
