Well you may notice this is my third posting about fish, so I will sum everything up for you It started out with a male Betta I had for about a 1 1/2? I wanted to give him some friends and was asking about good tank mates for him. Then my brother got me two female bettas. The one died and so I was wondering if the male and female could be together. Just two days ago my beloved male betta died My mom wanted to cheer me up so she surprised me with some fish I know I need a WAY BIGGER tank and I'm going to get one at the end of this month, I also know I need a heater which I will also get Right now in my tank I have, 1 Black Moor, 1 Algae eater?, 1 Female Betta, and 2 Mollies. What I need to know is how big of a tank I should get, and if either of my mollies look pregnant. Also what this little skinny dude is? My mom said the guy told her he eats algae and is in the Cat Fish family?? Oh also is there anyway to tell if my Black Moor is Male or Female? Molly #2 ( that fat one ) She has been siting near the bottom of the tank next to the one plant. She also appears to be panting? She seems like she doesn't want to be around or deal with any of the other fish. Thank You!!!!! Sorry about my reflection in some of the pics Mollies Female 1 Female 2 Group Pic Betta Black Moor Cat Fish???
