I'm restocking my 29g, I previously had 2 angels and some Nerites in there. Unfortunately they never paired up and the male killed my female, so I decided to re-home him in the end and start fresh. Currently I have one male dwarf gourami, as I just couldn't resist and a couple Nerites Thinking about adding: 6x Harlequin Rasboras 6x Kuhli Loaches 1x BN Pleco Is there anything else I can add without over stocking? And would these guys be compatible? Also if there are any special requirements for any of them that would help too, like sand for the loaches, ect. TIA, Kimberly.
