It's a 20g long. Stock: 6 harlequin rasboras 3 guppies 3 platies 1 albino BN pleco I just got the pleco 2 days ago. He was doing great until today, when I added an algae wafer into the tank. He found the algae wafer and started to eat it. I also put another algae wafer in the middle of the tank for the other fish, so they wouldn't try to steal the pleco's algae wafer. But 2 of the platies and 1 guppy started to attack the pleco! I did not know what to do. I took out those platies and guppy and put them in a container, about 1/2 gallon, just to get them away from the pleco. Now I don't know what to do! It's very late at night here. -Should I put them back in the 20g long? -Should I put them in one of my other tanks? I have a 20g tall with 8 skirt tetras, could I put them in there? I also have a 10g betta and shrimp tank. I know this tank is too small for a betta community, but my betta is very very peaceful and has never shown any aggression towards any of the shrimp or snails that have been in his tank before. Challenge the Wild (YouTuber) has a 10g with guppies, platies, and a betta (they get along really well), and his betta is very peaceful just like my betta (Angel). Should I risk putting them in there? If they start to attack Angel I could just take them out very fast. I really appreciate any advice or help! I'm so worried, I feel so bad for my pleco.
