I just got my betta, Odysseus, last week. The tank has been running since Thursday, Odysseus has been in it since Friday.
The gravel in the tank is black with some other, colorful pieces thrown in. I got it from Petsmart when I was getting the rest of the supplies. However, it's only been a week and the black gravel has started to lose its color! A few days after the tank had been going I noticed the water had turned slightly cloudly, regardless of the water changes I made, and couldn't figure out why; could my color-leaching gravel be the culprit, or is it something else?
Is this going to be harmful to Odysseus? If the gravel is losing its color I would like to replace it regardless, but if it is potentially harmful I will change it sooner.
Also, any ideas what to put in instead of the gravel, and how to make the exchange? I was thinking maybe black sand, is sand really as messy as I have heard? Is there a certain substrate that is best for growing live plants? I currently have a branch of water wisteria in there, it's not dying but I can't really tell if it's growing.
I'm still very new to this, so sorry for all the questions, but I thank you for your help and greatly appreciate it!
