reef tank

Hey guys! I am setting up a 75 gallon reef tank all the rock is cycled so will be able to add fish soon and was wondering how many fish could go in a 75? I am also planing on doing soft corals. Any fish recommendations will be extremely helpful!

So I am looking to get a new tank. I currently have a 20 gallon cube and 60 gallon cube but would like to upgrade to something bigger. I was originally planning on waiting a while to do this but the seams my 60 cube are starting to get questionable. I bought that tank used (for a steal) and...

Hello everyone, I have recently set up a 75 gallon aquarium and one of the silicone seals appears to have algae growing underneath it in a few spots. The tank has only been set up for three months and was never previously set up so it is almost brand new. I do not want to name the brand in...

How do you all go about deciding where to place your corals? I’m not talking about high or low light/flow, but more so where within the area of the tank they would succeed? I’ve narrowed down a list of possible corals I’d like to add, but haven’t been able to pull the trigger on any because I...

It pains me to write this but I lost 25% of my corals I was growing over the last 3 years in less then 2 months. The only person to blame is myself and that's the only way one can improve. Watching your coral die slowly is a painful site. What lead up to this and how can I prevent this in the...

Wondering how many fish you can have in a 32 gallon biocube that won’t be too heavy of a bio load on my corals. Currently have a clown and a six line wrasse but for sure wanting to get a yellow clown goby and a yellow head jawfish. Would like more fish then that but feel like that would...

So I’ve finally have been able to get my dream 150 gallon tank! But she’s a bit of a project so as much as I want to fill it up right away I have some things to do first . It’s already drilled, has over flow, came with a sump, ato water tank, and what I was told are two “China box lights”. I...

I just picked up this bubble tip anemone for a few bucks. Does anybody have an idea of what this coloration is called? I assume it's fairly common. I just like to know what colorations I have for all anemones and corals.

Hello I have gotten two female divided leopard wrasses about a month ago … they are doing great, however when they first arrived their color was bright orange whit and black . Over the past month the orange has changed on both of them to an ugly brown color. Neither one is changing to a...

Why do noobs feel the need to buy nano tanks? Despite the massive amounts of research showing they should be utilized only by experienced reefers. Every single day I see on here some noob having trouble with their 5 or 10 gallon tank and their massive parameter swings…fish, coral, inverts...

Hello, I am currently battling prorocentrum dinos and am making solid progress. I have a forest of GHA now, but it is now becoming problematic. It is housing stray dinos in it, while also suffocating my Xenia. Even though it is a competitor for the dinos, it is also a major nuisance. I want to...

good or bad? is there anything to be mindful of? any species that could be effected? so on and so forth.

Back in February of 2020 I started my fish keeping hobby and started out with freshwater. And after having so many small tanks I finally got a 10 gallon fresh tank. All I have to do to this tank is change the water and clean out the pre filter sponge. Everything else works it’s self out! So then...

Hello I have a 93 gallon mixed reef cube with a deep sand bed of about 3-4” in the back and only about 1” in front. I have had several newly added divided leopard wrasses that were very active and eating suddenly disappear? And I just had a new one that was swimming normally and exploring...

I have 4 zoas, 5 SPS corals, and 2 LPS. Most require moderate currents except for the 2 Birdsnest I have. It use to be a FOWLR. Im more concerned with the fishes as im running a mini protein skimmer and HOB filter with a GPH of 200 and they stay away from that area of the tank. Ive been reading...

I love the look of macro algae aquariums. I absolutely fell in love with @tigahboy.h2o (on IG) setups. They look so good and really inspire me to start a macro algae tank setup. I’d love to see your macro algae tank setups for more inspiration!

Hi, probably a but early to be worried. I bought a Royal Gramma yesterday which when added to the tank darted straight for the rocks. It did this in the shop and went inside of the rock there so i think its done the same in my tank. From what ive seen they can hide for quite a while my only...

Hello! I was wondering what the best sand sifting gobies/blennies/dragonets would be for a 20 gallon long reef tank. I currently have a pair of clowns, pep shrimp, snails, and saltwater mollies. thanks in advance! :D

I recently purchased a few corals for my 20 gallon reef tank. One of them is a green acropora. I have had it for a little more than a week and at first it seemed to be doing great. But recently it has started to lose a lot of color and looks kinda pale. If anybody knows what wrong with it and...

Hey all, I'm not sure if my fish are having aggression issues or if this is normal behaviour. Any advice is appreciated! I recently downsized from a 24g to a Fluval 13.5. In it I have plenty of live rock with many crevices, tunnels, and hideyholes, my corals (mostly small except for a "large"...
