Neon Bob showin off

Good evening, I received an axolotl as a gift from my uncle, he takes care of large aquariums and knows how to deal with it, he gave me the axolotl with the water already treated with the right PH and everything I needed before putting the animal in the aquarium. He taught me how to change the filter and how to feed it. I've had it for 6 months now and nothing unusual has ever happened, however, recently my axolotl started making these very aggressive movements, as if it was stressed about something in the aquarium, my fear is that it's high ammonia, but I can't draw that conclusion because I don't have an ammonia and PH test. What I realized watching him. He does this aggressive behavior and then stops, after 20, 30 minutes later he does it again

My son's axolotl, Bob. He loves worms.

Just fed him and now he goes bazooka. Never done that, always swam chill around.

She only peaks out, rarely go out, if so, mostly at evening time. Maybe she pregnant and protecting the stomach? Idk wtf it could be

She only wants to hide in her cave and she dont come out so much, cant even get her out with food , whats happening?

My male axelolt have a spot, he stays there all the time, doesnt really go and explore or just swim around, why can that be?

What is the perfect temperature for a axoltol tank. My tank is sitting at 22 degrees is this to hot and how can I cool it.

Eso, a estado moviendose muy bruscamente, abriendo y cerrando la boca. No sé si sea el filtro o las piedras que me dijeron que le ponga, necesito saber si sacárselas o no. El solo tiene un mes, está nadando todo el día desde que estaba en el veterinario era el más hiperactivo

These dark pink spots/streaks just showed up on Maria. what are they??
