I really REALLY want to upgrade my boys to a nicer tank each. Nero is in a 1.5 gallon, and Octo is in a 3gal.
What I'm thinking of for each boy is this:
Octo's tank will be ocean-themed! He already has a shark cave and a blue-green ball. Sand substrate - I already have about five pounds and I can add some more to a larget aquarium if necessary. Maybe add a pirate ship cave if I can find one small enough.
Nero's tank will be pirate-themed. He has barrels for hiding spots. Substrate will be sand as well, with some gravel accents.
Questions I have:
1) Is the filter that comes with the Minibow a good filter? Pros? Cons? I can't tell if it's an internal or external filter. Can I use a sponge instead of cartridges?
2) Is it possible to have live plants in a 2.5 gal tank? Or a 5gal? What plants do you recommend?
3) What heater do you recommend? I currently have the Marina 10W but I want something adjustable, if possible. The current heaters I have are pre-set.
4) Any ideas/suggestions? I was thinking of getting a snail, but I don't want to if they'll be harassed, even in a 5gal.
