Just got an email from my local fish club about some of the species that are going to be at the gigantic spring fish auction on Sunday and one of the fish listed was a trio of L236 (Hypancistrus sps.). I want to bid for them so much but I'm not sure whether I have room for them. I will definitely have physical space for them in my 75 but I have a 4" Gibby in it and I'm afraid he'd murder them. Now there aren't any fish in my 30 that would hurt them but I don't have much physical space for them. I could get them their own tank eventually but the biggest I could go is 15 gallons, would that be big enough for a trio with weekly 50-60% water changes? And let's say I put the trio into their own 15, if I wanted to spawn them could I temporarily raise the fry in there with them since I know plecos aren't really aggressive towards their fry at all for the most part. So what do you guys think I should do: 30 gallon with little physical room, 75 with possible aggression issues, 15 to themselves but fairly small tank, or not go for them at all?
