    I have asked this question many times over the past maybe 5 years of my serious interest in fishkeeping. I have not once gotten more than a half-hearted "I guess." as a response.
    PLEASE! If anyone has any possible answer, experience, or knows of anyone who might I would very, very much appreciate your presence. I very soon will have my tank set up and I am seriously considering putting these two species together, and if no one can clearly explain why I shouldn't, I most likely will end up trying it.

    These are the "optimal" (on average from researching) conditions to keep these fish in.

    Boesemani / Parkinson's Rainbowfish (close enough that i've combined them) - 72-82 F, 7.5-8.0 PH, 8-20 hardness. Top to mid level swimmer. Up to 6".

    Spotted Pictus Cats - 73-78 F, 6.0-8.0 PH, hardness 4-15. Bottom swimmer, generally non-territorial. up to 5".

    I don't know about you all.... But i'm reeeeaallly thinking these two might be compatible. But... why is it so hard to get a clear answer...? Is there something that I don't know about spotted pictus that makes everyone seem to avoid them?


    Is it safe and reasonable to keep some type of rainbowfish, example being Parkinson's or Boesemani Rainbowfish, with Spotted Pictus Catfish?


    Why or why not? Please again and thank you!

    I'll begin by saying I have not kept these two together, but we don't (or shouldn't) need to "try" something to know what the result will probably be. And to that end, these should be compatible except for one important factor, temperature.

    Pictus cats (Pimelodus pictus) need 22-25C/72-77F indicative of its habitat of flowing rivers and tributaries. More here:
    http://www.seriouslyfish.com/species/pimelodus-pictus/

    Rainbows (Melanotaenia boesemani) need warmth, SF says 27-30C/81-86 F.
    http://www.seriouslyfish.com/species/melanotaenia-boesemani/

    Parkinson's Rainbow (Melanotaednia parkinsoni) is not on SF, but Fishbase gives 26-30C.

    I would suspect the pictus would not be in good condition in such warm water. Reverse holds true too of course.

    Byron.

    Looking at more than one website I have seen a wide range of temperatures suggested for either species, the average that I have found by looking at different sources is what I listed in my post. It may not be exact but honestly I don't believe any one website will likely know for sure, either. I have seen the majority of Spotted Pictus information stating that they tend to be sluggish and eat less in the low to mid 70s, and are more active in the upper 70s to low 80s which is why it seemed that approximately 78-79 would be a decent overlapping temperature for the two.

    I would just like to ask...how do you decide this or that site is actually factual and not just someone's opinion? That is why members here rely on SF and Planet Catfish and a very few others. These sites are owned by ichthyologists, and even more importantly they have members who are trained ichthyologists that peer review. Anyone can set up a website these days, and promote themselves as "expert" while not having a clue.

    And since I mention PC as another reliable site...their temp range for P. pictus is 22-25C/71-77F.
