Baby. See it?

Rearranged my shrimp-loach tank again!!!

I trimmed back four or five of my plants ( they’d already grown an inch or so from when I trimmed them on Wednesday!!!! ) and replanted the clippings in a cluster in the back lefthand corner of the tank. I took one of the chunks of driftwood that has a huge anubias plant growing on top of it ( which has sprouted two separate branches since I bought it ) and replaced it with a driftwood arch that was way too small for my cory/tetra tank ( it’s only about two inches tall, but the noodles like low-to-the-substrate decor )

then I took the L-shaped driftwood in the back righthand corner and turned it upwards, placing the anubias driftwood on top of it ( giving the kuhli loaches more floorspace and the shrimp more climbing space ) and planted my one remaining feathery plant ( no idea what it’s called ) between them. It’s grown a good three inches since I moved it from where it had drifted to the top of the tank last week!

Surprisingly, the noodles ( kuhli loaches ) were very calm this time around! Usually they got crazy with my hand in the tank, but I think they’re finally getting used to the tank cleanings. Saw three of my shrimp, maybe four? out of the five(?) remaining.

waiting for the tank to clear up to tank proper pictures, and since I’m out of Aqueon water clarifier 😔 it might not be until morning.

Benefits of collecting your own aquascape materials:

Save a lot of money

Walk down the street with a large cobble in your hand, nobody catcalls you.

I mostly write about organisms and not the principles of fishkeeping. However people often ask me about two related phenomena, cycling and stocking. Aquariums are safe for fish and other animals because of the nitrogen cycle. This is what determines, moreso than the water volume, the carrying capacity of the tank. But many people seem to be confused - what is the nitrogen cycle?

'Cycling' refers to the cycle by which the toxin ammonia, which is excreted as waste by organisms, before it is turned to nitrite and then to nitrate by biological actors. In aquarist parlance 'cycling' refers to the process and duration of time, during which the nitrogen cycle becomes established and stable. Properly the cycle continues throughout the operation of the aquarium.

Ammonia, which contains nitrogen, is the principal excretory product of living animals, and they void it because it is a toxic byproduct of their own metabolic processes. Human urination is an example of a way in which animals lose excess ammonia, but other kinds of animal may excrete ammonia by means of different methods.

Fortunately other organisms can find a positive use for ammonia, which animals don't want. Their own metabolisms create nitrite from the ammonia they intake, by breaking it down and adding oxygen to the nitrogen. Then yet more microscopic organisms convert the nitrite to the similarly named and chemically related nitrate, which must also be maintained at low levels, but is far less harmful. Traces of nitrate are in fact beneficial to some aquarium organisms.

The nitrogen cycle originates from the decomposition of amino acid, and this is why test kits are available to test for dissolved organics, which are not themselves inherently harmful, but their buildup indicates strain upon the system. How much strain is acceptable depends on the kinds of animals that are living in the aquarium. There isn't really a single standard as to when there are too many dissolved organics, or even nitrate. But regular and sensibly proportionate water changes, help to keep both under control.

Because it involves the processes of different organisms, the nitrogen cycle is very obviously an ecological, as well as a chemical phenomenon. Both the natural processes of the cycle, and the technology by which the effects of the benign organisms are maximised, are known as biological filtration, or biofiltration. It is different from physical and chemical filtration, although the functions of filter media may overlap.

The good bacteria that are involved, colonise available surfaces throughout the aquarium. They are present on rocks and on substrates such as sand and gravel. Similarly they colonise sponges and various proprietary items such as 'bio balls'. At this point, I wish to explain the introductory principles of biofiltration, not to cover its different expressions. It is however worth pointing out, the more the better.

Stocking levels are problematic principally because the living animals themselves create strains upon the biofiltration. Furthermore they require inputs of food, excesses of which contribute to dissolved organics, and therefore the nitrogen cycle, when they are uneaten - thus, messy feeders create more bioload than other organisms, lowering the carrying capacity of the aquarium system.

Feeding behaviors thus determine the 'footprint' animals have on the biofiltration in their aquarium, moreso than their size. It is also the mass of an animal that contributes to its output of wastes, moreso than any single dimension, such as its total length. Another determinant is the metabolic rate of the animal in question, which determines the speed at which its wastes are generated and churned out into the water.

The nitrogen cycle is also why overfeeding is bad, because excess food must inevitably decompose. By definition, the aquarist can't be overfeeding, from the perspective of the nitrogen cycle, when the supplied food is being eaten; overfeeding as in overeating is a different problem. However if feeding your livestock and keeping them healthy begins to stress the cycle, then you have too much bioload in your aquarium.

Often in marine aquariums, 'live rock' and 'live sand' are mentioned. These terms mystify many people, although they are relevant to filtration. The rocks and sand in question are substrates already colonised by microscopic organisms, as play a role in the nitrogen cycle. All items already this colonised are thus 'live' biofiltration media.

Unfortunately there is a misconception that 'live' rock needs transporting from the sea. Such rock is shipped damp but emersed, killing benign and desirable organisms, and necessitating a period called 'curing' in which photosynthesizers are denied an energy source, and further mortality and decomposition ensues. The result is that only 'tough as boots' organisms survive, and some of these species are harmful to corals and such.

Clearly despite the appeal of 'live rock' as a ready made, natural reef, it's use is problematic and self defeating. A distinction just be made, between the use of 'living' filtration media, and the importation of artificially depauperate microenvironments for aquariums. It is better to take rock and sand from an established reef tank instead, to avoid unwanted guests. Although even impoverished live rock can introduce interesting and useful 'friends', these can arrive also from established, nuisance-free tanks

A counterpart to the use of live rock and sand in reef aquariums, is the Walstad style of freshwater aquarium. The Walstad type of tank is one in which living plants and soil substrates are employed instead of artificial filtration; more common than a strict Walstad setup, is a hybrid system that employs both naturalistic and 'normal' approaches in its running.

Sometimes it is said that planted tanks do not cycle, or that adding plants stops the cycle. Nothing could be further from the truth. True aquatic plants and the organisms called algae, play a role in the cycle, which is why algae bloom during the cycling period of a new aquarium, when the lighting is switched on. Adding plants to freshwater tanks, and macroalgae to marine aquariums, should be thought of as assisting the stabilisation of the nitrogen cycle.

Once I have the funds, I'm going to be setting up planted "fish" bowls (No actual fish tho just plants) as like, spells / living altars / etc. I'll post about it and all that once I get started. I already have one kind of started but I want to get more variety of plants, I currently only have 3 and would like to have more before then. Plus, they're not as full as I'd like with plants, I only have a few stems growing so far! It's probably a long shot but if anyone reading this has some aquatic plants they're looking to get rid of - for maybe price of shipping - let me know!

There's not a thought behind those eyes. At least he's pretty.
