Okay, so I bought a filter the other day for the fry tank.. and it isnt working well!! The water is a bit.. scummy at the top..I dot know if that is the right word to use.. but there is a film on the water at the top. Not sure if thats from the filter not working or what the problem is. I lost one fry today. Not sure why. Should I keep them in the fry tank (there are now 13) or shouel I transfer them to the community tank in hopes they survive? There are like 5 or 6 plants and 3 ornaments 2 which the fry can fit in but the adults can not. I do not want to lose any fry.. but at this point not sure which would be better for them.. and where they would have a better survival chance!!
