Super interesting ! Mine are usually only in the bag for like 1030 minutes , but with how little water is really in there I wouldn ' t be surprised if that was long enough for ammonia to build up . Then again , I think my tank might just be cursed . I put my male guppies in there and today found two of them had died . I have never lost a single guppy in the tank they were in with the females . I ' m starting to consider setting up a new 20 gallon long , though I don ' t know that there could actually be anything wrong with the tank itself considering most fish do fine . There are just an abnormal number of deaths in this specific tank . <| sep |> I got banned from rsports for replying in a rmodclub conversationThey talk about rthedonald leaking . But thats some serious biasedmod leakage .
