ok heres my current situation.... bought a 10 gallon tank and have 3 fantails and 3 mollys.... ones prego. tank is set up and the fish are doing good, the only problem I have is the first goldfish we got is a big bully to everyone.... hes tried to eat the tail of the black moore we have and actually ate the three baby mollys that wound up in the bag with our other mollys when we bought them.... (I figured theyd be too big.... they were about this size __ and the goldfish is only about this size _____________ ....so.... anyways this setup is just temp. we are moving in about 4 months to a bigger place and I will be getting a bigger tank...(probly about a 50 gallon.... we plan on keeping the ten gallon for our daughter, and it will have just the fantails in it. when I get my 50 gallon I want to have guppies and mollys....nothing but..... so.... what would be a good equipment list and a good layout in order to have healthy happy fish? oh and I love the babies, so any info on that would be great....I cont have more than the two tanks so I can't have a separate tank for the babies and if I can figure out a way to separate the tank into maybe one big section and one little section then that's fine, but how big should the sections be and how would I do it?..... I love fishies! I absolutley love livebearers...id rather have a big school of tiny fish then 2 or 3 bigger fish......
