Seaman said:What type of filter are you using, and do you know the gph....because that will help to know. You will definitely need to find the pleco a new tank, it will get a foot or more if housed propperly, otherwise its growth will be stunted and it will suffer, plus their poop factories!!I would also suggest moving the guppies, livebearers are hard to control, population wise. I would say assuming your filter is adequite, then its safe to add the 2 cories (dont forget to take out the pleco and probbably the guppies). Another thing, you can "overstock" kinda(to a point).....as long as your filter can handle it, and you dont mind doing more/more frequent waterchanges...and the fish arent "cramped" and running into each other or overly large. Just my opinion

sorry i have no idea what gph is :thud: but as i posted above i have 2 power filters running: one whisper 10 (again, it's going to be replaced this week by an aquaclear 150 - up to 30 gallons) and one penguin bio-wheel mini (up to 20 gallons)
regarding the livebearer's fry (ies), i already know some fish/pet stores where i can take them to.
thanks everyone for your inputs!
