Hi there! I'm new to freshwater tropical fish keeping and I've been in the process of cycling my tank. I currently have a golden apple snail and a mountain minnow from my old tank (I was told that the minnow would be ok in the warmer temperatures?). I have been having issues with bright green algae growth - the picture attached is only 5 days after I cleaned the glass! I'm not sure if this is normal or not? Also, any advice for what tropical fish would be suitable for my 38L tank once my water is ready would be great! (38L, tropical, 1 apple snail, 1 mountain minnow) Thanks!!
