    I would watch more of this! This was actually really interesting and useful. I've been considering adding new discus to my 4+ year old fatties... but I need them to be big enough to hold their own, but I was thinking it would take forever. Now I feel like I have options.

    This man takes care of 10+ aquariums, with many different fish, and barely any of them have died. Me? I’ve had a fish tank for about a week, 30 gallons, and 2 of my GUPPIES died.

    How many gallons is the big tank? Also is that the only light you use above that tank?

    Should really be using gloves when handling any kind of coral , Especially zoanthids, pallytoxin is not fun. Landed me in the hospital for a week. Haha, that plate coral is so slimy also.

    Mine loses prime when the pump loses power and then when it starts back up, the overflow doesn't start back up, I made it to your exact method yet it doesn't keep flowing after. I don't want to need another power source to run the tank (it costs heaps more here in australia). Its getting frustrating

  47. Scott Loudermilk

    Scott Loudermilk2 days ago

    i like the idea of a small tank set up like this with brightly colored shrimp. or a few really nice guppies, they are small and i think would accent this miniature environment. and, ive never seen you do anything with guppies. i like them myself. red dragon guppies and bright yellow shrimp against your black substrate and green mosses. perfect

    Iam sure glad we don’t cull humans because there hair line is almost in the back of there head. If you think we should kill anything that isn’t normal for any reason then you to should maybe have been culled also.

    Also wouldn't be the worse thing to check ur par levels on the rocks and sand where u have placed corals. Do it once and adjust ur led color settings and u will always know what u have.

  56. Phil Cavallini

    Phil Cavallini2 days ago

    For the plate coral what I have done in the past is use a pvc fitting to elevate the coral just above the sand this allows the coral to expand fully and better circulation around the coral itself.

    Another tank going in the best direction for me... Really like communities! Smaller fresh water fish, bigger fresh water fish (but still not monsters) like you tree tank (don't remember the galons), and this one... So freaking cool ! And really like the rock formation in this one, it's actually a pretty natural shape.

    Why are puffers so damn entertaining? Great upload, progress of those little dudes will have me tuning in. Usually solitary so seeing a school of 3" long puffers will be so cool. Take care mate, Hope the family are well?

    Bro, Frank may have made it okay for YOU to love fish and act this way toward fishkeeping, but YOU made it okay for me to do the same. Thank you, Frank. I cant offer anything else, except the chain reaction of Frank is definitely reaching out.

    You need to do a predator tank next as you now have a reef tank so a predator tank sounds cool with kevin and a eels, trigger, grouper etc.

    Hello, awesome video. Question, can you use lava rocks in a saltwater tank?

  76. Austin Webb

    Austin Webb2 days ago

    That triggerfish will 100% eat your coral. It might be instant or take weeks or months but he will eat it at some point and once he does he will go to town. In a short amount of time he can destroy a large amount of coral.
