Hello fishlore, it has been a while since I have logged on so let me give you an update. The 29g is gone due to a massive leak, and has been replaced with a 20g long. 2og long 2x silver lyretail mollie (1 male, 1 female) 2x gold panda mollie (both male) 2x twin sidebar platy (1 male, 1 female) 2x mickey mouse platy (both females) 1x red wag platy (female) 10g Blue veiltail betta Now, I would like to get rid of a minor fry problem in the 20g long. I have only seen 2 fry, but I know that can change fast. I can get rid of a few fry, but in massive numbers fry become difficult to find what to do with. I know my betta would enjoy feeding on the fry. I am not worried about him getting along with the platies, as they have no long fins. 1 of the lyretails is my concern. i have seen him nip at other mollies occasionally, but only if they bump into each other while feeding. I have 2 fish caves and 8 plants for them to hide in and around, and i know the betta cannot catch them. I want to move the betta from the 10g for 2 reasons 1.) fry control 2.) the 10g is unheated, but i am in texas in the middle of summer with the tank next to the window and the temperature is maintained at 72 degrees even at night, so I am not to conerned. I can also move the only male platy into the 10g by himself to help keep them from breeding. would you recommend doing this?
