    Too much rock??

    Hey folks! I’ve got a 55 gallon set up as a peninsula. The tank is about 4 months old, and my question today is: can you have too much rock? I am worried that my tank won’t allow enough swimming room for additional fish, as I’ve already seen some minor aggression (territorial, clowns chase goby...

    Wondering what tank would suit my goals

    I would like to get into the hobby with a 55+ gallon tank this summer. I’ve been looking at the Waterbox Marine X 90.3/110.4, or Red Sea Reefer 300XL/350/425XL. I will be living in an apartment for the next 6 years at least. Here are the fish that I’d like to have at the very least: Clownfish...

    Would a golden dwarf morray work in this setup?

    I am looking to see if a golden dwarf morray eel would work in the setup I have now. It is a 32 gallon biocube, I have 2 clowns and a small melanurus wrasse (he’s small now and I am rehoming him when he gets too big). Would the tank be too small to sustain him? Liveaquaria says 30 is min but...

    I got two male Wrasses? What do I do?

    I thought it was pretty rare to receive a male leopard wrasse but I just got two potters wrasses delivered and they’re both male... plus there is a smaller male leopard of a different species already in the tank. What do I do about this? Will it be a problem? How big does the tank need to be to...

    What are the TRUE dosing instructions?

    I've always wondered what manufactures really mean when they give dosing instructions based on "gallons." For example, Korallen-Zucht and Red Sea give dosing instructions for their additives in terms of X ml or X drops per 25 gallons. Gallons of what? Is it based on the rated tank size (my...

    4 vs 3 feet long 75 gallon tank

    Hi guys I thought I would ask the nice people from R2R before pulling the trigger on this one, I'm probably blinded by how nice the new tank looks. I got a nice chance to swap my 4 feet 75g by a 3 feet 75 gallon, and the reason why I'm considering that is because I dislike my current sump setup...

    Tank size necessary for a self substaining copepod population for a dragonet.

    I had a dragonet when I first started the hobby in a 30 gallon tank. It was my first fishkeeping mistake. It was no where near established, so the dragonet eat for a few weeks and I could tell it wasn’t going as good as it could have, so I gave it to a friend who had a good copepod population...

    Would a powder blue hate being in a 75G?

    Hello all! I think I know the answer to this,.. BUT! Years ago, back in the 2000's when I first got into this hobby many places would recommend a minimum of a 55 gallon for a powder blue. I had one in my 180 SPS reef for years, and it is my favorite fish ever. These days I only have a 75G...

    75 vs. 90 Gallon: Tank Size Dilemma

    So I'm trying to decide whether my next tank should be a 75 gallon or a 90 gallon. I've had a 75 gallon before, so I'm very familiar with its dimensions and ease of care. I'm also limited to a 4-foot tank due to the space limitations in my current home. I am interested in the 90 gallon due to...
