Yeah the shark went back to the store today (without refund or exchange). When they sold me the tiger barbs they told me plenty of fish would get along with them once my tanks was done cycling. I went back today to return the shark and all of a sudden the only fish they could recommend for my tank size to go with the barbs were more barbs. That will be the last time I step foot in that store.

So I came home frustrated and stared at my new 30 gallon tank that was now home to a whopping 3 small tiger barbs. No clue what my path forward would be since my whole plan with this bigger tank was to be able to fit a nice variety of fish. My other tank is just a 10 gallon community tank that i was having a blast with but quickly reached my limit on how many fish would fit in it (2 marigold sword tails, 1 red swordtail, 1 lyretail molly, 1 pearl danio and a pleco.

That is when I thought of switching my two collections around. I wouldn't mind having a barb only tank if it was just a small tank and i would move all my community fish to the big tank which would allow me to add a bunch more variety of fish (was really wanting an angel or two).

What do you all think? Can the 10 gallon fit ~6 barbs and if so will they be happy with just 6 of them and no other fish? And any suggestions for what to add to the community tank when it is time to switch (waiting for the 30 gallon to cycle first). Or is my whole plan a bad idea?
