Thanks for your reply. I understand the pleco will grow into a monster soon enough, and will rehome once needed. But, as of now I feel he has plenty of room. If I do introduce more cats, it makes sense losing him sooner than later. I just went through a horrible crash months ago. Bought the tank off somone online who took two weeks before he let me pick it up. Only to find it covered in brown algae, and still full of about six inches of water. Only once home, did I find there were 7 cichlids in there! Poor things had cloudy eyes, and it took a lot of work to get them healthy enough to rehome (months actually). After a lot of continuous cycling to clean substrate and get everything balanced, I introduced new fish. The tank went wild again. So, I lost several raspboras then. I didn't realize cats like schools. I guess after years of keeping tanks (20+ years), I just took for granted what the pet store said. Lol. Total naive mistake on my part. I've seen smaller sunfish varietes that grow between 2-6 inches. Was thinking of introducing maybe only 2. Most darters are also mostly bottom dwellers, so once I get more cats that would be out. Any other suggestions on nice bright fish? I like calmer tanks and plants, which is why I let go of the cichlids. And breeders will become a hassle since I dont have anyone near that will take them off my hands often enough. Lol. I just feel stumped this time. It's making me really miss my love of brakish puffer tanks again. Once more, thanks.
