Hi! I have a 29 gallon tank. Wich is the home to one royal pleco one gourami one molly and 3 neon tetras. The pleco is 3inches right now and in the future I heard they get really big. Any Idea why fish would be good with a full grown pleco because once it gets big I will take out all the fish but te pleco. And keep maby a cupple fish. Do you think this is a good plan or will the pleco not fit in the tank when it gets big??? Tanks!
