    Finally finished cycling my 29gal and have my first Green Tiger Barb. Only added 1 Barb to avoid a mini cycle. Everything is going good after 24hrs, actively swimming and seeking food. Parameters are temp-77f Amm-0 nitrite-0 nitrate-5 pH-6.4

    How soon could I add more? I know keeping them in a school of 6-8 is ideal and don't want any of them stressing over having too little numbers. I'm confident I've built a strong enough colony to handle a couple more fish.

    This is my first fishless cycle, and only my 2nd ever tank (one other betta tank doing great) Just looking for some experience advice :)

    Were you dosing ammonium chloride for the fishless cycle? 1 barb in a 29 gallon is going to do nothing, you’ll actually need to add more fish soon to avoid bacteria die off.
    The amount of bacteria you have depends on how much ammonia you were cycling with. More than likely, you can add a small school right off the bat.

    Yes I was dosing dr tims ammonia to 2ppm. What size school would be safe to start with? I also have a lot of filtration, a biowheel 400 and a large sponge filter to handle the bioload

    Tiger barbs tend to be a bit nippy in small numbers. It might be a good idea to go ahead and fill out your school of at least 6 right away. 6 should not over load your new cycle and should also be enough of a bio load to continue feeding your cycle.

    It should be a big enough school to keep them from nipping each other too.

    Honestly I’m my opinion, get the fish you want, complete what schools need to be complete.

    So when your ready to add just add the fish in a span of 1-3 hours. I added 20 fish in a 55g in a span of 2-3 hours to avoid any problems.

    Reason doing this...if you buy fish first and a few weeks later you buy another fish(es) you risk the introduction of parasites or other problems to your tank.

    Thank you for the advice, I went and purchased the rest of the school and have them acclimating now. A total of 7 should make for a nice school.

    You are very welcome. Yep, 7 should keep them happy instead of nippy :D
