Stocking Advice For 30g Tank

    Hi All,

    I have a 30g tank that has been up for roughly 3 yrs.
    I am in the process of stocking again after moving some fish over to my 20g and would appreciate any advice/suggestions.

    Currently I have :

    4 zebra danios
    4 redfin tetra
    2 upside down catfish
    1 balloon molly (and three Fry)
    1 molly
    1 common pleco

    (Yes, I am aware that my pleco needs a bigger tank and yes, I plan to rehome him when necessary. He was a rookie mistake, bought him on advice from lfs 3 yrs ago and was absolutely clueless as to how big he would get eventually. He is currently 20cm)

    Would this current set up work or any suggestions on additions?

    Water parameters perfect, well filtrated (2 biological filters, one electrical filter) well aerated, weekly 25% pwc, ph 7.2-7.4

    Have to mention that I have given up on gouramis as I still cant get them to survive longer than 3 months :(

    Any suggestions or advice will be much appreciated

    Common Plecos need 125+ gallons due to their size at full growth.
    Beware the tetras might nip at the fry, just a heads up.

    I'm glad you have a plan for the pleco.
    What are your exact water parameters. Perfect doesn't give any info.

    Nitrite 0, amonia 0, Nitrate 40

    Nitrates at 40 is not perfect. That's where it starts to become threatening to your fish. You probably already know that though.

    At 20cm he is already too big for your tank

    Try to get nitrate below 20ppm

    I would just add 2 more danios and tetras to complete the schools

    Dimensions? 40 ppm is too high, I would keep them at no more than 20 ppm.

    I would try a apistogramma of some sort I have a similar tank
