I'm really worried about Alex :[ I was hopeing that you could help...! He is eating normal...and he's active and being his happy self but I noticed a dark black spot on his body that is just a black puffy spot...I really have no clue what it is! Is there something wrong with him...? I'm really worried about him!!
I wish I could help you out with this question, but I make most of my stuff and some of my store bought stuff is pretty old and I don't use filters on my tanks 3g and less.
You should post this on the main board, there are lots of pretty smart folks on this site that would love to help you out.
Sorry I couldn't help
Hey, me and my sister are new to this whole betta stuff. And my sister has this 2 gallon tank "Top Fin Aqua Scene desktop aquarium" from petsmart which comes with an air pump and she's wondering if that whole kit is good or if she needs to get a filter. If so, we were wondering if the Tetra Whisper In-tank Filter is any good for them. We've been told that it isn't, but we've read reviews that it is good for bettas so we're confused. Also if you could recommend any good heaters under $25? Please helpp, thanks!
