alright so my 20g got poisoned via dead pleco, and now the only fish left alive from rapps is a very mean male escondido, he killed 2 plecos, another male escondido, and one of the females, the other died from the poisoned water. so what i was wondering is after i get rid of the 2 common plecos i have(fins are getting nipped) what should i put in there as a bottom dweller really anything besides plecos. just shoot some stuff around because i dont know much about bottom dwellers, my ph is around 7.6 and my water is 15 dh.
