A friend at work is starting his first fish tank with help from me. When I ask him what fish he wants, he doesn't have a clue other than to tell me he wants "super cool bada** fish."
The tank is 30G. I suggested pool filter sand as his substrate but we haven't put it in yet so any alternate suggestions are welcome. I have come to terms with the fact that I have become a bit of a fishy control freak and pool filter sand is MY personal favourite and I like a natural looking tank, but I also don't want my tunnel vision to result in him having a fish tank that I love but he hates.
So as of right now the only thing in the tank is water and I showed him how to get the filter up and running... Not sure what brand the filter is but it's an HOB. I can post the exact brand when I get to work tomorrow.
I have told him he can "borrow" my betta to cycle the tank and once it's done, I'll put him back in my tank.
As for stocking, are there any suggestions, keeping in mind his desire for something somewhat aggressive? I showed him the profiles from here for firemouth cichlids and kribensis, and suggested that a male and female pair of kribs would be better for his tank size than the firemouths... He said he really liked the kribs better as well. So for now, that is what we're planning for... But if anyone has other ideas, I would love to hear them! I don't really know much about non-peaceful fish other than bettas.
