What are the danio, Zebra Danio? They need a larger group. It is not something I would ever do, mixing gourami in with danio, but...i use to have a dwarf gourami in my tank before the Serpae Tetras, (well i got them after my dwarf pasted away). and he was fine there was no problems with fin nipping at all, he even can up for pats. i even got him a girlfriend, but she then died of that dwarf gourami diseases and then the boy followed. (i love dwarf gouramis, but the disease only lets you keep them for a couple of mouths )
my black widows are very peaceful, for being only three of them.
so if i didn't have the black widows and the Serpae Tetras, i could have a gourami, maybe two?
Just to reaffirm the Serpae issue, they can be nasty to any sedate fish particularly if the group is small. I had 5 in a tank and they were removed for this. I like to consider 8 as a good starting point for shoaling fish (the tetras) partly to keep the numbers up initially and partly in case of loses along the way... that way you may end up with six rather than having six and having to add a few if there are loses.Hey i was just wondering if having 3 danios, 2 brushnoses, 3 black widow tetras, 5 Serpae Tetras, and 9 neon tetras. is too mush for a 35 gallon tank (i am not 100% sure on the tank size). Also i would like to know if, i could put in a gouramis?
