Is this too many rocks? Do I need more open sandy area on the bottom? I plan on having yellow-tail acei, yellow labs, and maingano.
Well, the way it was explained to me is that "caves," per se, are not really what's important, but rather a lot of nooks, crevices, and especially walls. You need to "think in terms of breaking the sightline of the male on the substrate." When you think of it that way, vertical surfaces and horizontal ledges/overhangs are just as effective as "caves." Some photos of great mbuna tanks I've seen don't have any "caves" at all, but just a lot of big rocks creating vertical surfaces that a fleeing fish can hide dart behind or around. That said, I have 7 obvious caves in the front (see yellow circles below), and a couple more in the back that aren't visible in the picture. Plus, there are lots of vertical surfaces and a few horizontal ledges that can be used to break the sightline during a chase.Idech said:The amount of rocks looks good to me but I would arrange them to have more caves and cracks, so any fish that needs to escape a chase or hide for a while has a place to go.
Great point about the algae scraper! I didn't think of that. I'll make sure there's enough room. I don't really need too much space though.... I've always found that an old credit card works about at good as anything for an algae scraper.Swim_Shady said:You will want to ensure that you have room to get an algae scrubber/scraper between your rocks and the side panes. That way, there is no need to move or re-arrange rocks once you get algae buildup on the glass.
The arrangement looks fine to me otherwise. My Acei always ignored the rocks in my tanks and stayed more in the upper half of the water column.
Any photos of examples? All the photos I can find of mbuna tanks look more like my trial rockscape than what you're describing.DJRansome said:You want to use smaller rocks as you climb because indeed you do need a lot more nooks and crannies, and the smaller ones are better. Not too small on the rock size...half the size? Remember the males are going to want the ones on the substrate with walls (I see 3 of these), and the females needs dozens of places like a maze up higher to escape when being chased.
Plenty of substrate left, but I would definitely leave room for the scraper and also a "python-width" on the substrate all the way around the rock piles.
You don't have rock piles in your 75g using my rocks. I think the depth of a 75g is a little under 18". If I leave 2.5" of clearance in front & back, that leaves about 12 inches of depth. Using my rocks, I'd basically be stacking them straight up, one on top of another. Like a child's stack of wooden blocks, it would be highly unstable and would inevitably tip over. Like I said, it appears I bought the wrong kind/size of rocks. Any suggestions on what I should buy and where? I had a devil of a time finding these ones.DJRansome said:I have rock piles in my 75G without touching the sides, and I have a 3D in tank background. The points of the rocks in the base can come close to the glass but not touch and you want the python to be able to access right and left of the point, so that all substrate surrounding it can be siphoned.
Can't do pictures now because I have not replaced the rocks (correctly) since I moved...my tanks are not picture ready. I might be able to find old pics or other pics, stay tuned.
Seems impossible to achieve any height that way. I'd end up with the largest, heaviest rocks balanced precariously on towers of smaller rocks. I've been staring at these things for hours, and I'm out of ideas.Deeda said:.....Try putting the smaller rocks on the bottom of the tank and using them to support the larger rocks horizontally or tipped at an angle......
Well, if it goes by what I like, then I'm happy with the rockscape in my photo above. But I'm more concerned about what the fish will like.DJRansome said:It always takes me several days to get something I like. It will happen. What about if you go diagonal tipped up and leaning on each other with all of them? Or think in those terms?
Nice. I like it. What size tank is that? Is the rock pile centered between the front and back glass? Or is it closer to the back? Approximately how many inches are there between the front glass and the rock pile? Also, where are the fish? Thanks!Sinister-Kisses said:This is my mbuna tank...I'm still playing around with the placement to get it "just right", but you can see how much of the tank is full of rocks, varying sizes, creating lots of spaces for fish to hang out.
