I'm starting to plan well in advance. We're about a year out from purchasing a house, and I'm thinking that I would love to get a lotl tank set up once we do. I don't know how much space we'll have or things like that, but want to start thing and planning for this now, since I have a feeling it will be a chunk of money to get everything together. What I think I'll need: Big-ish tank: at least a 40 long or something at least 4 ft in length Filter (obviously, but what type) Heater (though would rarely be used, probably for fishless cycle and then unplugged unless something really strange happened in the house) Aquarium chiller Missing anything? How many can I house together, and do they like each other's company? Is there any chance that a BN pleco could live with one, or would it be too small and become food? Is there any chance a medusa pleco could live with one, or would it be too small or the temp difference be a problem? My fiancé really wants a sunken ship for the tank, any concern with that being in there? What type of requirements are there on how the tank needs to be designed/scaped? Any other information, tips, or suggestions on things to read/places to look for information would be greatly appreciated.
