To remove the cyanobacteria from my plants (Ceratophyllum demersum, Elodea sp. and Salvinia minima), what could be done? Is there any brush for this? I usually take these plants to a separate bucket during my partial water change. On this bucket, also, I take the "old water" from each water...

My term paper about my brine shrimp is almost finished... soon I'll defend the thesis. I would love to record the presentation and try to put English subtitles, although I know that probably this will require some authorization. Where we live, most of the year is hot (above 25º C) but, during...

I feed my betta with Poytara Betta (Brazilian food that probably doesn't exist outside Brazil) four times a week, besides one-day fasting and during weekends I feed with live juvenile/adult brine shrimp and/or tiny BSFL (from my cultures). A few hours before feeding the shrimp for the betta, I...

When I'm trying to find bettas with shorter fins, I didn't find. I only found it when I already bought this betta... This is the first time I'm using a sponge filter since I always used hang-on filters with Sera Siporax Mini and some pads (the white "wool" that's used for filling patchwork).

For some reason, the hole on my betta's dorsal fin simply disappeared. Besides this, I reduced the photoperiod to 7 hours a day, also adding more plants (Ceratophyllum demersum, previously treated with potassium permanganate), as well as removing the cyanobacteria from rocks and the dry...

A few days ago, I detected a hole on my betta's dorsal fin. Today, however, I suppose that this hole disappeared. This seems so weird to me. Note: the date format is always dd/mm/yyyy. Also, I added several Ceratophyllum demersum, besides removing more detritus and cyanobacteria. Today I...

Today I edited my last Artemia franciscana photos (date format: dd/mm/yyyy):

How much do I feed my betta? Is possible to estimate, including for live food? Live food I give artemias and tiny BSFL.

My siphon is like this: I'm in fishkeeping since 2012 and this is the first time I got cyanobacteria in any tank. I don't see any sense in cleaning all to start another new tank, even more, since it took more than one month to cycle and here in Brazil there's not any good biological...

Today, during my Major internship, I taught practical classes involving brine shrimp that I culture... well, these creatures were remaining from my term paper during February - March/2023 and now they gave me descendants... Tomorrow I should teach the same class in another classroom. Also, I'm...

Today I recorded another video: The water became less turbid, also improving even the illumination (yes, I'm using a simple desk lighting yet... with an old fluorescent lamp):

I saw some cases where people killed cyanobacteria with azithromycin. It makes sense to use this or not? A few days ago, I also placed a curtain on the window door on that's side of the aquarium, then this should help with something. Today I made a partial water change and removed ... well...

What percent should I use for daily water changes? How could the cyanobacteria be eliminated? Should I change anything related to the feeding or not, such as giving more live food to maybe help with recovery? What are the food directions? Maybe I'm overfeeding him, also, with betta food and...

Then, today I perceived a small hole on my lovely betta's dorsal fin, as you can see below: This is the setup: • Size: 15.74" length x 11.81" height x 9.84" width, 7.29 gallons; • Substrate: 11.02 lbs gravel nº 0 (Aqua Pedras); • Heating: Roxin® HT-1300/Q3 50 W, adjusted to 26 ºC; •...

Well, I forgot to post these two videos... Yesterday I gave some tiny BSFL for my betta. However, reading this article, I saw that BSFL fat is about 30 %. This fat level is simply huge for my fish. Am I correct or I misunderstood anything?

What species is this grass? It looks like the grass from my mother's house.

Today I gave a ride to a neighbor and I made some money, although the roads here are terrible. Giant potholes, dirt roads, several (tall) speed bumps, and the valetas (I don't know if there's an English word for this). I also sold some adult artemias to a fishkeeper. Well, it's a 2013 Fiat...

I'm sorry for your loss. What was this black thing around his snout? I had a Boxer for 13 years. She passed away last year and I wrote even poetry about her. Well, I'll try to translate to English: Thirteen infinite winters Rests here, the creature Sweet soul And bravery from a murmillo...

Besides trying to figure out my internship extreme bureaucracy (it's easier to get a tourist visa than this), yesterday I tried to draw my Betta splendens: The picture: Also, today I tried to pick more tiny BSFL for my betta (I have a BSFL culture). Tomorrow I should give for him and check...

Well, let's bring updates? Probably my tank's now infested by cyanobacteria. I don't know what could I do about this issue. Also, these bubbles appeared. May be the aquarium glass, but the fact is that there're bubbles on the rock... Once again, this last weekend I fed the betta with...

Maybe for the fact that being a Biology student and being on fishkeeping since 2012, I like several organisms, of different kinds. I started with this hobby involving live food in 2013, when I started culturing Ulomoides dermestoides, but eventually, this thing collapsed. Well, at least today...

Today I fed him with some brine shrimp, but I realized that he's selective in some way (my zebra danios loved and ate even the largest ones). He prefers to eat the smaller ones, because the bigger ones he swallows and spits out. I even thought about giving daphnia, but these organisms are...

Well, usually my betta ate the isopods without any problems. This betta I didn't feed any live food, yet.

Does anyone know if small white isopods would be okay for bettas as live food? I didn't find anything relating to nutritional value.

What would be the problem with bloodworms, exactly, that doesn't apply to other larvae? Or this would be applied to other aquatic larvae?

Finally! Well, I'm sorry for so many photos. Indeed, it's so hard to take some good pictures, because the betta is agitated, besides the fact that there's some light reflection. Today, I measured ammonia and nitrite, getting 0 ppm. Well, it's cycled, I think. Also, I did a partial water change...
