Hi folks, I've been frantically searching, yearning, learning, YouTubing, scanning this forum. I'm going nuts. I got the bug bad. Addicted, insane and feel like I'd do ANYTHING FOR A FIX!!!! I've had a saltwater tank since October (Fluval Evo 13.5) it's cute and it's still getting started but I. Want. More. I do this with all my hobbies but once I got into fish I found my true love. So here's the issue, I'm getting older and I'm it. No one to help, lug big jugs of water for me or look after my tank when I can't (who needs vacations anyway). I know I'm gonna end up getting another tank. I KNOW I should just stick with my little Fluval but I won't. Here is what got me started to really go crazy. I want a Pink Spot Goby. I fell in love with one at my local and I actually go visit it. They told me I need at least a 30 gallon for it. I also know that I won't be getting much more fish in either of those two tanks. I just learned fish would rather have long than high tanks. If I got the 40 my plan is to drop in a Fuji Cube all-in-one so I can have a spot for all "the works", I'm baffled by sumps and this seems easy if expensive. Or, could I just do a hang on back filter like a Seachem Tidal 55/75. Or do I suck it up and learn about sumps. Then I'd have to drill a hole. I know this is all over the place but I guess my question is what would you do with all your knowledge and my skimpy wallet - get a 60 cube or a 40 breeder? I think the cubes look cool but probably the 40 is more practical. And if you suggest one please advise on some modifications I should get to make it work. Finally, thanks to everyone out there who takes time to answer crazy posts like this. I've got another one brewing already ;-)
