In my 12 gallon tank i have 4 platies, 2 harlequin rasboras, 2 gold barbs, 2 ballon molies and 6 neon tetras. As for decorations i have gravel, some sort of plastic bush, a pot, 1 medium sized plant, and 1 big tall plant that reaches the top. My gold barb is full off eggs and i dont want fry because of the space in the tank. But will any survive? How many? Thanks.
