This fish resembles the Brazilian fish known as traíra (Hoplias sp.), a fish known for its sharp teeth and its aggressive behavior.

Well, today I graduated... this was a simpler celebration since I'm in a hurry and I must get the undergraduate documentation as soon as possible, for doing evaluation and more. Without coronation, unfortunately. @Rocky998 This last fish resembles the Geophagus brasiliensis. What fish species...

While I was at gym today, I saw this cool car: It is a Chevrolet Omega, Brazilian version for the Opel Omega A. The model had good sales, also being used as taxis. My uncle had one and it was one of the most comfortable cars I ride as passenger, comparable only to a Honda Accord.

Does black soldier fly larvae work for trouts? When I was living in Florida, even during winters with cooler temperatures, I had several.

Yesterday I had to take a trip on my mother's Toyota Etios 1.3 with manual transmission (this ugly thing). The reason? Simply I had to take printed forms to comply with the "complementary activities". Despite the "complementary" word, these are other obligatory classes to get the degree. Also...

Besides thinking about my dreams, I'm trying to figure out what is happening with my brine shrimp culture. I suppose that they are dying by age since they don't live so many months. Then, I used a siphon and removed so much detritus, that was with a bad odor (anaerobic bacteria). Last Sunday...

Today I made a practice test on Duolingo. These points are enough for entering in certain American universities. The main advantage is that the exam is much more affordable than the TOEFL (just think that the Brazilian real devalued about 50 % in 5 years). By doing the TOEFL practice tests...

Well, I know that since the last post, it has been about three months... but who cares? The thesis was approved and the artemias from the culture were transferred to the current cultivation I still have. I can call them "House of Term Paper". The cyanobacteria issue is under the control as...

When I was living in Florida in 2019, I also saw a cane toad. He was eating the flies around the dead fish, in a park next to the limit between West Palm Beach and Lake Worth Beach. These toads became a pest in the US, probably thanks to people thinking in using them as biological control on...

Still exploring how master's admissions work in the United States... my dog escaped today but, fortunately, I found her thanks to a neighbor who caught her... because Sofia simply was at her house entrance. Okay, this doesn't make sense. This is what happens when the aquarium's light turns off...

My mother loves to cultivate Phalaenopsis sp. Gardening here is very uncommon, so it's a surprise for many people around here. A few days ago, I was going to our deposit at night, when I got slightly scared (seriously, because I had seen these animals several times here) with another Rhinella...

The good news is that probably is not so far from getting a good TOEFL score (I'm practicing with the TOEFL GO). Also, today I did another partial water change and recorded this simple video:

The shrinkflation is even worse here in Brazil. Interestingly, this phenomenon doesn't affect all items equally (for any economy you can imagine). I even thought about doing research about this applied to the Brazilian economy, although I'm not an economist (and I don't intend to, I find)...

Usually, yes, even in cities considered "safe" by Brazilians, although even so, it varies by region (Northeast and North are the worst regions in crime rates, while the Southern region is the best). Is possible that this can improve for now where I live (São Paulo state) because at least the new...

A few days ago I had some difficulty with sleeping, simply because my dog didn't stop to bark, this at late night. I walked and, next to the wall (here in Brazil our homes are as little castles, thanks to high crime rates), I started to hear some noises from someone trying to assault the garbage...

Currently, I just watch Netflix series and/or movies, indeed, although not so much. Many times, I prefer to read articles or books (mainly on Economics and History). We don't have cable TV and the free-to-air TV is usually terrible, also. I used Excel for doing the term paper (doing the...

Yesterday, after I reached home from the gym, I witnessed a roadside hawk (Rupornis magnirostris). Since it's hard to this bird of prey reaching close to home, I tried to take some good pictures... Also, today I removed some of my tank's decorations and siphoned one more time (although...

I believe that I'm almost finishing my undergraduate, although I'm a little confused about M.S. in the US. One thing at a time. Also, today I was preparing the material which I'll use for the presentation at an event next month, about... my artemias. Since I must improve my English speaking...

As I said before, my paradise fish went fine with the zebra danios I had in my old 10-gallon tank. The issue is that the fish committed suicide after I transferred him to another recipient since I was trying to treat the poor fish.

It seems that the dorsal fin is rotting:

When I was living in a town for my undergraduate studies (on a kitnet... I don't know if this exists in the US), I was using a 1980s fridge, and the monster was loud sometimes, even when I was using earplugs for noise reduction. Anyway, I find your fridge cool. This ad below is from Consul's...

I'm sorry, I didn't understand. Today, once again, I gave my betta more artemias (Is there a plural of "artemia" in the English language?). Tomorrow I should give a tiny BSFL to him. Also, I saw this cool guy (Caracara plancus): These birds are opportunist creatures, eating carrion (including...

Today I decided to do something weird... singing with my brine shrimp: I usually like to eat fried tilapia fillets. They are expensive here (despite being farmed domestically), but I like it. I tried fish known here as "cação" (and nobody knows if this is a shark or cartilaginous fish) and I...

Trouts are farmed in some places in Brazil, in cooler areas such as Santa Catarina state. Oncorhynchus mykiss (rainbow trout) is the main species cultivated. Near my home, I saw fish such as catfish Pimelodus maculatus, Prochilodus lineatus as well as characids Astyanax sp.. I also reported...

A few days ago, I made a video trying to speak English about my "ultra-low-cost" Artemia franciscana culture: These creatures became pests and I didn't know the reason. Besides going to gym (once again) and doing some research relating to universities programs, today at least I got one...

Well... when I found bettas with shorter fins, I already bought this one. I never thought that a betta would be able to figure out that biting his fins would result in alleviating weight. What could be done?

How could be possible for the betta biting his own fins?

This video below I recorded a few days ago. What would be this thing on his caudal fin? Curiously, this thing disappeared and another similar thing appeared, but on another region from the fish's fin. Yesterday, I also noted that there is a rip on his caudal fin. However, it seems that the...

Commuted for about 22.1 km to another city on a Fiat Mille... just to take two forms for my mother's appointments (for some reason, politicians love to build several speed bumps, without markings and some standardizing... even on highways). Yeah, Brazil's bureaucracy is powerful, and titanic...

Besides this, I noted another small hole, this time on his tail fin... Measured ammonia, nitrite, and pH, where I got 0, 0, and 7.5, respectively. Temperature is 26 ºC. Yeah... well, once again, I'll increase the frequency of partial water changes.

Let's bring some updates... Well, a few days ago I noted a different thing on my Betta splendens. What would be this red thing on his upper right operculum?

What was his age? I'm sorry for the loss. I never had any case of betta jumping from the tank, although I had a betta in a basin outside and he disappeared. I don't know if Betta splendens is able to have some affection. He shows enthusiasm even when my dog looks at him and I suspect that he...

Beautiful fish paintings. I'm also playing Age of Mythology: Extended Edition (always on Very Hard and with BOTs). Although they should care more about historical precision (fire lance, while a very good siege weapon, still didn't exist in Ancient China, that's anachronistic), I love to play...

Well, when we do some artwork, the artwork can carry things from our personality. I personally find them cool. That you said remembered me some days ago, when I showed some of my drawings and the person said that they seem "sad". This was curious for me since even my former therapist never said...
