I set up a nice 20 gallon tank at grandmas about 3 weeks ago, upgraded from the 8 gal I gave her. About a week and a half ago I noticed this goop/slime growing on the filter biowheel and lid. It started out as just a small patch and in the last couple of days it has really started to grow and...
They fan them to keep them clean and to keep water flowing over them. Most shrimp will do this.
I always thought nature was funny that way, how they can be a freshwater animal, but need brackish when young. Or can survive in either wtaer type.
Yeah, for the most part the darker color comes from breeding for darker color or lighter color. I have some high grade and some low grade shrimps, but don't really breed selectively.
The darkest, purest red ones are bred to be that red and are often high grade shrimp. The lighter pink speckly is what the color tends to be if they are not bred to be darker.
Substrate does come into play, but I have a light substrate and very dark shrimp.
I've had both females and males that were lighter in color. All depends on the strain of the shrimp and what they were bred for.
They get darker before a molt and have lighter shells right after moulting.
I have kept many crabs over the years. Vampire crabs, fiddlers, Hermit crabs, and Halloween Moon Crabs.
Fiddlers are the ones I had the best luck with that were a true crab. They really enjoy their water and they love climbing all over whatever you put in the tank for them. They will eat...
I keep seeing this 1"per gallon rule thrown around in a lot of places. To me this seems a little bit off.
By this mindset I can keep a 10" cichlid in a 10 gallon tank and it will not be crowded. Or 10 1" guppies which is really a lot for this size of tank. By the tine you get into the big...
Gradually turn down the thermostat on your tank heater. Acouple degrees every week or so until it gets to your regular room temperature.
My guppies do just fine either heated or coldwater tanks.
