First I want to thank everyone that helped me with my cichlid issue. Unfortunately he died last night. So now it's time to recover. In my 31.2g cube style tank I now have the following: 1- jurapari cichlid (just leaned that's what it is) 1- adult angel fish 7- Cory cats (different types) I would like to cycle my 29g tank (rectangle) with a 70g fluval sponge filter. Question is this. Can I put the cichlid and the Cory cats of same species (about 3 of them) into that tank and add something with a pop of color? What else could I add. Question two is if I do this the 30 is now open to add to. The stock would be 1-adult angel 4-Cory cats. What could I add? My son really likes the honey gourami and the blue gourami. He also like fish that school. So I need help with both the 29 and 30. Thank you.
