I've never heard of that. Goldfish, yeah - but cichlids? I could be wrong but AFAIK most of them make their territory in and around plants. LHG, gwa and dwss will be able to tell you more than I can though.
What sort of chiclids are you talking about keeping. Large boys, Malawis and most south americans will not co-habit with plant especially if you have breeding pairs etc. If you want plants then you wont get away with much more than kribs and stuff like that.
Cichlids and planted tanks. Many cichlids are not plant compatible rift lake cichlids do not have plants in their natural environment so count them out. All the dwarf cichlids from south america are plant compatible but some of them - apistogramma and blue rams can be tricky to keep.
Angels and discus are quite peaceful and plant friendly.
The majority of the smaller central americans are plant compatible - rainbows,convicts, honduran red points, sajica and salvini. These fish will dig when spawning as they move the fry to pits. If you have real big diggers amongst these varieties choose hardier plants such as swords vallis onion plants and cryptos.
Larger central americans and south americans such as severums and uaru - plant eaters. Jags terrors midas devils and texans etc are not only large but notorious diggers and plant movers.
All that said however it can be down to the individual fish as i keep an oscar in a planted tank with out too much destruction.
Which type of fish are you intrested in keeping and I can be more specific.
I'm not sure what I want to keep yet My tank has finished cycling, It's a 55 gal, and I planted it when setting it up. I was aiming for a tropical community with Tetras, corys, etc. However, as I've learned a bit more I've realised that my water is quite hard, GH is 180 and KH is 80, (PH is 7.5) GH seems to have risen during the cycling from the 140 I measured in the tap water probably due to evaporation in the aquarium. I'd rather keep something that suites the water, what do you think?
I'm in Rip Off Ireland (It's not in the Location drop down menu)
6 Platies with about 18 babies 1 Golden Gourami 1 silver dollar (I know, it was the last one in the shop) 2 Pearl Gourami 2 Neon Blue Dwarf Gourami 1 Sunset Dwarf Gourami
I've got a planted tank and, as far as Cichlids go, I've been advised on very good authority (thanks LHG ) that Flag Cichlids, Keyhole Cichlids, Blue Rams (from good British Bred stock) and Angels will be fine in a planted tank.
So far, I can report he's actually spot on...unsurprisingly.
