I currently have 4 marleri julies (1 male, 3 females) about 8cm each in a 29, but looks like I'm able to get a 36 by 18 by 24 65 gallon upgrade. I have plenty of rock on standby and I am wondering what else to add. I'm thinking a group of Black lamprolagous (in store at about 6-7 cm long) and maybe 1 or 2 other species but I am open to any suggestions about any other additions that I should consider. I want species that look very different color and/or shape wise and I do not want species very likely to hybridize. all suggestions and advice appreciated. I hope to have the tank set up within 2-4 months
